Not sure. The Phoenician, I think.[/quote]
If I remember where the Phoenician is you are probably going to be closer to Quiltz, The Apple, and Sew from the Heart. Partly depends on whether or not you have transportation, too.
35th Ave, on Northern is about a mile from me, and does have a lot of fabric.
I also like Sun Valley Quilts out in Sun City, and have visited many of the shops in town. We also have one down south in Awatukee that is owned by 3 guys, "3 Dudes Quilt Shop".
Also depends on what kind of fabrics you are looking for. Many of the shops sort of "specialize" in specific types of fabrics. Some have a bit(or a lot) of many.
