Pinwheels Fabrics is in Bryant on Hwy 5.
http://www.pinwheelfabrics.com/ Very nice shop. Take exit 126 off 30 You drive down Hwy 5 thinking there can't be a quilt shop here but then there it is, a nice big converted house on the left, watch for the sign.
I would stop at Marshall's first and then back again on my way home.

If you ask to buy an unopened bolt you get a big discount, they are in the back on the shelves and you can browse. But you can't buy bolts on Saturday, the reps are not there. I don't know of any quilt shops from Marshall's to Pinwheel.
Little Rock has several machine dealers that sell fabric and notions but no big quilt shops.
