I've checked online and about a dozen companies sell quilting-sewing products called "Wonder Tape." They all seem to have the same characteristics: double-sided sticky tape 1/4" wide, washes away with first washing. I'm interested in trying a few different brands to see if one is easier to peel off the top paper. I love this stuff, but getting the top paper off is challenging, even with sharp fingernails. It's worth it, though. I don't know what brand I have since I've lost the package and there are no markings inside the roll. Even though though getting a grip on the top paper is challenging, it's worth it to keep a long seam straight. Here are some web sites with different brands.
