The process. Amazing paper mâché recipes and advise can be found at ultimatepapermache.com
I used the paper clay recipe from the site, and a gesso recipe she gives if you watch her YouTube video series on making masks. I highly recommend them. The paper clay recipe calls for the use of boiled linseed oil which is toxic, but I use Tried and True Danish oil Finnish, which is a polymerized linseed oil, food safe(!!), and available at Woodcraft stores. My local Woodcraft had it in stock, and for being food safe and worry free, also only needing two tablespoons per recipe, it's well worth the $14 price tag. It will last a looooooooooooong time.
