There is an absolutely wonderful shop in Marion called Sew Biz! It is on IN 9 and very near to where many of the Quilters Hall of Fame activities are held. Sew Biz also generally has some special activities going on in the store during that week. You can check out their website...just google Sew Biz Marion to get to it.
Honestly, I have been going to this LQS for about 15 years. They have a huge selection of beautiful fabrics, lots and lots of samples made up, and the friendliest and most knowledgeable staff around. I live about 15 miles from there and I know I'm in there at least 5 or 6 times a month. I love to take the classes they offer, too. Be sure to check them out!
