This was my first time experimenting with paper mache clay. My goal was to create a smooth layer to even out the bumps of the normal paper mache layer underneath it. I think it went alright over all. This is the recipe I ended up using: 1 large mixing bowl filled almost to the top with small bits of newspaper, boiling water, 3 4oz bottles of Elmer's white glue. Pour boiling water over the newspaper to cover. Let sit over night. Drain water. Pour bottles of glue in and mix to combine.
This did make a pretty decent clay. My one regret is not ripping the newspaper into smaller parts. Also, it took a long time to cover, as well as to dry. I will need to sand it to make it smoother so I can add my last layer of regular paper mache. If anyone has any advice, please feel free to leave it in the comments. I hope this works out, but if it doesn't at least I will learn something from it.
