There are some great quilt shops in the UP. Tahaquamenon Fall was mentioned and about 12 miles from the falls is a great quilt shop, Village Quilt Shop, just outside of Paradise, MI. If you visit the Soo Locks, there are two quilt shops in Sault St. Marie. There are a number of great shops in Upper and Lower Michigan. I don't RV, so I'm not sure how they are located in regard to parking an RV. I'm sure you will enjoy all the sites of Michigan.
