The very first quilting class I took had a portion on fabric selection. The teacher said that most fabric manufacturers make the same design in three levels of quality. The highest level is sold in quilt shops, the medium quality goes to Joannes, and the lowest quality goes to Walmart and discount stores. As most of Joannes fabrics now are from China you really have to be careful. I compared some Snuggle flannel purchased several years ago with a recent purchase and the difference was heartbreaking. The one from China was several inches narrower and shrunk many more inches. After washing it was also thinner.
As there are no Hobby Lobbys west of Denver I would always take an extra suitcase on vacation for a major shop there. Two years ago they underwent a major cost cutting change in the fabric department and now I rarely find one or two fabrics to buy.
The best place to find quality fabrics now is in my stash!!
