/cgl/ - Cosplay & EGL

Has anyone used heat n' bond on stretch fabrics? I keep following the instructions on the packaging and nothing sticks very well, and I'm not sure if it's my material, the fact that my iron is probably on its way out or because my ironing board is too squishy. I just tried a test swatch and set my iron to kill and pressed it for much longer than recommended and am waiting for it to cool to see if it holds any better.

I'm trying to bond really thin jersey knit to a uniqlo sweater that's about the same consistency as a mid-weight jersey knit.
