I specifically bought a much sturdier frame, reinforced in the middle, because thick slabs of paint can cause the canvas to bow and buckle. I’d been doing shapes without molds, using masking tape, and I wanted to experiment with using extremely thick slabs of paint.

I was hoping to make even thicker slabs, but I did begin to see the limitations of being able to cleanly pull up the masking tape from very thick slabs. The amount of paint getting pulled away starts to feel pretty unwieldy!

These slabs ended up as thick as a 1/3-inch however!
