If you’re like me and enjoy assembling 37 microscopic pieces of fabric into something that hopefully resembles a dog, person, or llama in a sweater—this stuff is magic. I use it to build my appliqué masterpieces one tiny ironed layer at a time. The best part? Once your Franken-dog is assembled, you can just slide it off and fuse it to your quilt like a boss. No sticking, no scorched disasters—just smooth, glorious precision. Honestly, I love it more than I love some people.
