In person the advancement of the work is quite noticeable, but I'm not sure it's as visible in a photo. Eevee was very determined to stay on the burlap. It's sort of funny because Yuu *loves* the burlap before I start work on it while Eevee only notices it once work has begun.
Type 6 plastic is the same type used in "Shrinky-dinks". It is very common in take-out packaging and also Styrofoam. I colored the plastic with permanent markers and, once shrunken, they will become parts for stitch markers and jewelry.
