Joanns mostly. Followed by quilt shops, HL and WM, depending on where I can find what I like. I have a couple shops I will buy from because they are super nice and their prices reasonable, unfortunately they a 45min/ hour drive away. The LQS near me, not so friendly so I avoid them. I have quilts made from WM fabric that are going strong after 20-30 years and had some with LQS fabric that wore and frayed. It;s not so much where you buy your fabric but the quality of the fabric you buy
