Having lived in both Michigan and New Hampshire, I can safely say that Keepsake is nothing like any quilt shop you have at home. Lots2do did a great job of mentioning the non-quilter attractions close by and that area of our fair state is absolutely gorgeous in any season. The scenery alone is worth the trip.
Just as a side note, New Hampshire also has a Quilt Sampler featured shop (2011) if you are going to be in the Henniker (Concord) area. It's called Quilted Threads.
