Someone sent in a tips from Fons and Porters the other day. The adhesive re-inforcing circles used on sheets of paper that have been prepared for a binder works great. They used to be loose and you had to dampen them to get them to stick. Now they come on a waxed paper sheet and they peel off. Pull a small amount of thread to the top of a spool and/or a bobbin (works equally well for both), apply the donut-shaped piece and voila! Mess gone~
