This is an EXCELLENT show - over 400 quilts, and the same quilt cannot be shown twice in this one! Quilts submitted are juried by request or just for show according to maker's desire.

I've not taken any classes at this, but have heard many of them are very good. Sharon Schamber was there last year teaching.
The quilt shop is very nice, and the atmosphere at the show itself is wonderful. If you have time to tour the village it's quite charming as well. Don't miss the sewing machines in the museum! This will be my fourth year going, and I know it'll be great as usual.
