I also shop at Joann's once in a while sometimes its simply a time thing or like when I lived in GA there just wasn't another fabric shop close to me. Joanns and Hobby lobby were it. I really disliked going into the Joanns there because the customer service was so horrible. The Joann's here is totally different. I am also on a very very limited income so sometimes that's it. I will say here in VA beach the one quilt shop really doesn't have the kind of fabrics I like using . And the help in there wasn't the best. I know people who love it. So I found Fabric Hut in Norfolk . Not too too far for me to go every few months since I have to save. I really wish I could pack it up and take it with me when I move.
I think the best thing to do with fabrics is learn how fabrics "feel" . Doing that has saved me money . I may like a print but will pass it up if it doesn't "feel" right. Since I have been sewing for more years than I care to think about it comes as second nature to me now.
