I actually have two articles that will probably be posted today – I hope all of you who have subscribed to these posts don’t mind getting two emails in one day.
This article is a guest post from Ari Kahn. It was originally posted as a comment on another page. Ari has helped to create the fabulous Mardi Gras floats that appear each year in Mobile, Alabama. (Did you know that’s where Mardi Gras actually started? I didn’t.)
Purely by coincidence, Ari’s comment appeared just a few days after I read 3-D Wizardry: Design in Paper Mache, Plaster and Foam, by George Wolfe. (The book is now out of print, but I managed to snag a reasonably-priced copy on amazon.com). In Wolfe’s book, he mentioned the process of making floats and large paper mache beasts, like dragons, using cardboard and contact cement. I searched everywhere online to learn more about this process, but I couldn’t find anything. Then Ari’s comment showed up, almost like magic.
Unfortunately, the designs of the floats are guarded like state secrets, so Ari couldn’t send photos showing how the process is really done. And I can’t show you the photos from Wolfe’s book because they’re copyrighted. So we just have to use our imagination. If anyone knows any more about making big, hollow paper mache sculptures using this contact cement process, please let us know.
I’m just now finishing up my second video about the wolf’s head sculpture, showing the sculpting of the eyes and nose. I’ll post it later today.
And now, here’s Ari:
I am an artist living on the Gulf Coast of Alabama who used to work on building Mardi Gras floats. You may not be aware of it but Alabama, specifically Mobile, was the birthplace of Mardi Gras. (Sorry, New Orleans. Better luck next time.)
The floats in Mobile parades tend to be larger than those used in New Orleans, and change radically each year according to the theme of the parade. This means a constant flow of large papier mache sculptures to attach to the float. I thought that the way we built them would be of interest to the folks here.
First we start with a simple wooden or PVC pipe armature. Over this we build up the shape of the sculpture with torn strips of corrugated cardboard, saturated with a latex water-based contact adhesive. (I don’t remember the brand name right offhand, but it’s a pale green in colour and it might have been 3-M.)
We would coat each side of the cardboard and allow it to dry before tearing it into strips or sections. One nice thing about this adhesive is that it’s waterproof. (You can use the old-fashioned brown contact adhesive, but it requires solvent clean up, takes longer to dry and the fumes are toxic.) Don’t use the cardboard from waxed cartons as it won’t work. Thin single-ply corrugated is better than double-corrugated or double-layer as it’s easier to shape.
Once the general shape is achieved we would smooth out the surface with torn sections of thin chipboard also coated on either side with contact adhesive. The best type of chipboard to use for this is the flimsy, cheap stuff. The nice thing about using the contact adhesive is that there is no drying time in the sculpture itself. Once you apply the dry cardboard and chipboard to the surfaces, they’re ready to go.
Over this we would apply a layer of torn white butcher paper that we would adhere with either wallpaper paste or wheat paste. This is to give that surface a final smoothing and a surface for painting, and paint doesn’t stick to contact adhesive very well. For paint we used ordinary exterior-grade latex that we would custom tint with powdered pigments.
These sculptures were very strong and durable. After the parade we would remove the sculpture and store it so it could be reworked next year. Some of the pieces we were using were many years old and were still going strong. I’ve seen these sculptures come through storms with flying colours. You can use this method to make very large sculptures, or smaller ones. I’ve also made smaller ones and covered them with layers of blended papier mache that I made from recipes I found on the Internet. (Sorry, I didn’t know about your site back then.)
I used to have a life-sized classic Grecian-style statue in my garden made this way, covered in my own blend of artificial stone. I made this from paper pulp mixed with cement and silica powder (also called flowers of silica). Silica powder is basically an extremely finely ground sand used mostly in iron smelting. This mixture makes a very nice “stone” facing that I finished to look like marble. After sealing it with a standard concrete sealer (and regular applications thereof as needed) it stood for 5 years without any cracking or deterioration, internally or externally. Well that’s about all. If anyone has any questions, drop me a line.
… Some of the societies Ari has worked for are the Infant Mystics, the Mystic Stripers, the Knights of Revelry, the Order of the Polka Dots, the Order of LaShe’s. You can find out more about the Mobile Mardi Gras here.
And back to Jonni…
Thank you, Ari, for giving us so much timely information about how Mardi Gras floats are made. And the comment about your garden sculpture is also really interesting – the “stone” coating sounds very similar to the rather expensive foam coat I’ve been thinking about trying lately. Your recipe sounds better, actually.

do you know who sells large paper mache objects…animals..buildings…golden gate bridge..im having a function for our local food bank and the theme is SAN FRANCISCO…food will be accordingly..sour french bread..crab.chowder soup.. looking for paper mache decorations..
Jonni, thank you for posting this on it’s own little page. I’m very flattered, and most appreciative. I wanted to mention that lumber and PVC piping aren’t the only items you can use for an armature. Before I used to work on the floats, I used to do creative makeup and set building for local community theatre. When you’re working on a low budget, you learn to get creative. One thing we used to do is raid the dumpsters of construction sites for broken sheets and cutoffs of hard pink or blue insulating foam. Sometimes the guys that worked the sites would put these aside for us if we asked them. (And maybe bribed them a bit with a nice box of Italian pastries. Down here Krispy Kreme may be king, but it’s amazing what a few cannoli and zeppole can do- with maybe a nice thermos of Italian-roast coffee to wash them down with.) We also used to search the dumpsters behind electronic and department stores for packing foam. (And I’m not speaking of the packing peanuts. Although those can be used as filler if contained in bin liners or other plastic bags.) And yes, we did on occasion raid the local recycling centre’s bins for foam as well. We just looked upon it as end user recycling. One thing we also used to do on occasion was to use commercial spray-foam insulation (not too often, this two-part stuff is expensive and never comes out of your clothes) over various-sized bin liners stuffed full of crumpled newsprint and taped together. This allowed us to create things like rocks and cave walls. After the foam had set up, we would carve it to shape and cover it with a good layer of papier mache. This works wonders when building “stone” walls, as I had to do seemingly ad infinitum during a production of Camelot.
On a side note, a friend who saw the sets hired me to do smething similar for him. It seems that he belongs to the Historical Reenactment/Living History Society, and makes shoes and other leather goods for sale to other members and the public. Apparently part of the rules is that you have to have a period-correct tent or building to blend in at the event. He had designed a small shop to fit on a trailer (look up tiny houses on the ‘net and you’ll have and idea of what I’m speaking of) and he wanted me to make it look like it had been built during the late medieval period, with “full-timbered” framing and a “stone” foundation all made from carved foam covered with papier mache, then coloured to look like stone (the “wooden beams” were just painted red like they would’ve been originally) and water-proofed.
I realize this might’ve gotten off-topic a bit, but papier mache is such a fun and interesting subject I do tend to drone on about it. There’s just so much you can do with it! Do you know in the past they even made carriages and furniture from it? The possibilities are endless.
Right now I’m working on a grave marker for my uncle’s cat who passed away recently from cancer. I can’t really use papier mache in this case as the maker might be trod upon from time to time, so I’m going to have to make it out concrete and reinforce it with something that won’t rust or rot. The only thing I can think of is the material that they make emergency sandbags. I’m not sure what it is, but those things seem to last forever, so I’ll try it. I’ll try to take some photos if I can remember to do so, and if it is okay with Jonni of course, and isn’t too off-topic with regards to papier mache.
Thanks, Aryea – great tips. And never worry about getting off-topic – I do that sometimes, myself.
Hmmmm. This is interesting. I’m actually more interested in his use of silica powder and cement to make a stone texture.
I did a little Googling on silica powder and found that diatomaceous earth (commonly called “D.E.”) — the stuff used in pool filters and available at any pool supply store — is essentially silica powder. It’s made up of 85% silica and trace amounts of alumina and iron ore (according to Wikipedia). Uses — aside from pool filters — range from mild abrasives to reinforcing filler in plastic. It’s also relatively inexpensive with a 25 lb. bag selling for around $20.
I’m always interested in new techniques, and while I don’t know if I’ll be doing it anytime soon, I just may have to try out this method and see how it turns out. If and when I do, I’ll be sure to post pictures here.
Thanks for another interesting post.

Yes, please do keep us posted on that stone idea. I’d like to find out more about it, too.
What a nice surprise to see randomly drop in to this site (been popping in an out for over a year) and see an article on my native city.
I adore Mobile Mardi Gras even though I’m miles from the Gulf Coast right now.
Again, what a treat!
It does sound lovely. I’m out here in Oregon, so I may never see the parade, but it sounds like such a treat.
Thank you both for sharing this! Fascinating something I might like to give a try to, in a small subject
Be sure to give us the details, as you discover how it works. (Photos sure would be nice…
)
