I live in the Houston TX area and my very very VERY favorite quilt shop here is Painted Pony n Quilts in LaPorte TX.
It's on the southeast side of Houston towards Galveston and I'm on the southwest side but I gladly make the 30 mi trip to this shop. We have a couple of good smaller shops on the SW side but if I want to shop a LOT I head to PPQ. They are always helpful, have all the latest fabric lines and the BEST selection of reproductions, batiks, 30's, kids fabrics and just about everything else you can imagine .... great book & pattern selections
If you are in the Houston area, don't miss PPQ !! :) :)
