location? And what is your budget (meaning can your guild afford to pay travel expenses?). We are in the KC area and have had several great programs from from quilters that are within easy drive time--if you are close enough, PM me and I'll send you their names.
One we did last year and plan again this year is a member UFO challenge--our president offered a prize for a UFO (over 5 yrs) finished up and entered into our guild show. We had a lot of fun with this program as everyone was encouraged to bring a UFO and tell it's "story"--there was a baby quilt that the recipient is now 35! And one member in her 70's had blocks that had been started while she was in high school! One member had a project that she'd started in a guild workshop years ago and lost the pattern--several could help her with that. Just a real fun program and no cost.
