Sounded so easy but truly this stuff is like working with stiff brittle fiberglass batting. First I bought a 24″ square piece and 16oz jar of rigidizer. Not nearly enough rigidizer to do even 1 form. The ‘blanket’ took it all in and I barely had enough to wet a 16″x6″ pieces.
No instructions came with any of it so really had to guess on how to “squeeze” into the blanket and hope for coverage.
Beware it is sticky, itchy, not soft or easy to form. Wear a mask and wear gloves. I think I am going back to low fire clay.
