Im a swap hostess and I can tell you it varies from person to person.. Some members send only the items to be swapped and some send something - fq, extra sqs of the swap, measuring take zippered bag, quilt book, soap, chocolate bars, $5 gift cards, templates, blank thank you cards, needles, extra postage, keep the change for gas $, handmade gifts: pins, pin cushion, potholder, funky chicken,notebook cover..
It is not mandatory by no means to send anything. it is considered a nice gesture for all the work and our time that goes into 'hosting' the swap.. But I cannot lie, i love the goodies.. :thumbup:
