I have been to all three. QIAD downtown Paducah is small but lots to see and super friendly. Hancock's of Paducah is huge with every fabric known to quilter there. Marshall's is my favorite place to shop. I go there about every six weeks or so. I over buy because I know what the price of the fabric is selling at the quilt shops and it's hard not to buy. Once you see the fabric at Marshalls, you will feel comfortable buying it online. Ask to be put on the email list. Only the front of the store you can have yardage cut from bolts, the back you have to buy whole bolts. A sales rep will have to write up the ticket for the whole bolts. I deal with Sharon but all of them are super nice. Look in every nook and cranny at Marshall's I have been many times and many items I didn't see the first few times I went. Caryl Beyer Fallert has a shop and open studio in Paducah and don't forget the Quilt Museum and several quilt shops downtown. I would plan on two days at Paducah.
