Years ago when making garments for the growing girls; I would shop Hobby Lobby, Hancock's, Cloth World (when it was around), Denver Fabrics for the best cheapest priced fabric. Throughout the washings seemed like all 6 would hold up with the grind of kids and washing. Now that I do garments for the grands: I still shop at Hobby Lobby, Hancock's, Jo-Ann's, Denver Fabrics for the best cheapest priced fabrics and online (even tho I am not crazy about online with cards) Fabrics.com, CT.
When the local LQS was going out of business; I bought many fabrics I would never buy at retail for 70 % off and put them in my stash and they wash beautifully as I used some in the quilts for the grands for Christmas.
