We have 3 Walmarts within reasonable driving distance from our home. I will not shop at the closest one because it is poorly managed and never seems to be clean. Having said that, the store recently became a "super Walmart". They enlarged it and added a grocery store. I haven't checked it out yet, but if the management is the same, it won't be long before it is in the same condition---just a larger store.
I drive to one of the other 2 stores and I always check out the fabric dept. I have purchased fabric for charity quilts at WM. For most quilts, I purchase fabric at my local quilt shop. WM has some good quality fabric---just not a good selection. Quilting is not a priority at WM, so they don't devote much space to it.
We travel and always stop at WM for driving breaks. I enjoy walking through the different fabric depts. The difference in depts. is very noticeable. The metropolitan area WMs tend to have much smaller fabric depts. than the ones in the less densly populated areas. They sell more fabric because there are no local quilt shops. WM is in business to make money. They carry what sells.
