hey magic, what are you corpsing with besides glue? and water? cheescloth, nylon stockings? tisue paper? if you want a good rigid and hard pice use like 1 glue to 1-2 parts water. If you just want to make the glue go further and having a dense hard material isn't as important, try a 1 glue to 4-5 parts water. Also depending on the thickness of the corpsing material, you'll want a heavier glue mixture for heavier materials like linen or cheescloth but a thinner mixture for things like tissue.
