So many different fabrics: baseball jersey, nylon windbreaker, sweatshirt, cotton, t-shirt, mesh football jersey...
When I cut out the nylon, I tried to iron on the same light weight interfacing that I use on the t-shirts. However, it just puckered and wrinkled the nylon--so, I pulled it off. The nylon fabrics in the blocks are not stabilized. I was worried that they would not quilt up easily, but they worked just great.
I love this pantograph for masculine quilts. I use it a lot! It's
