I searched on how to remove no sew tape residue from clothing. The easiest solution was the paper towel remedy. Just lay the paper towel over the residue and iron over it.
This worked a treat for me. Change the paper towel often and use a single or double thickness only. My DH used duct tape to hem our daughter's school skirt! So lots of very sticky residue left on the fabric. Took about half an hour of ironing to remove it.
