NCfleur, When I took my first Color Class, 10 years ago, the teacher told me that Walmart and Joanne's had similar quality
of fabric, then Hobby Lobby, then LQS fabric. It depends upon
the quilt that you are making. If it's for a donation to a Charity, I'd used fabric from Joanne's and Walmart. If it is for a special person I will buy at my local LQS.
If you are making a heirloom quilt and are having it quilted by a Long arm quilter, I would definitely use LQS fabric.
I have bought from Walmart, Joanne's and LQS, plus Keepsake
quilting. I hope this helps in your decision making. Eiltcoq.
