It seems they did "figure" it out, because they didn't even offer a sample, and said,"Yes it does work to line hair clips", the minimum order is $55". Okay, but when I requested a quote, I specified that I needed a tape to bond fabric to wood (not to line clippies!)
Very strange. They just assume it's for lining clippies now. I ordered some anyways and it didn't work for what I was using it for.
