i always give a hostess gift either a packet of machine needles, hand needles (if i know the quilt by hand), or a FQ.
i did another theme swap and i put in 6 inch strips of fabric for everyone in the group (about 2.5 yards of fabric) but only 2 other people in the group aside from me sent in fabrics to swap.
so even though it was a suggestion for the swap hardly anyone did it.
