I've been a member/board member of several 503c quilt guilds over the years and none of them required on site making of 'charity' quilts. In fact, we made them at home and turned them in at meetings during Show and Tell. The current guild has a group of dedicated members (about 12-18) who meet monthly for 4-5 hours to assemble, sew, or complete quilts to be donated. Many other members sew them only at home and bring them to the meetings.
