Place a ball, about the size of a marble, made of the yellow tacky stuff ( teachers use to hang all kinds of things on their classroom walls )on your sewing machine. Mine is in the front right hand side at the top where it does not interfere with anything. I hang my small seam ripper there. . Just push the seam ripper into the yellow ball and it's stuck. Now I know where at least one of my seam rippers is handy. Yellow stuff can be removed at any time with no residue left.
