thanks for your replies... I did starch this fabric and I probably did not starch the others. I started using startch because I thought that is what I was supposed to do to get good cuts... but if the tape won't work that puts the end to the starch. If I use the magic sizing with that effect the tape sticking? Is there anything that I can do now after I have starched to make the tape stick? Like if I wipe it down with a wet towel???
