I agree, with in reason. If I have a purpose for purchasing and supporting my local quilt shops, then why not?! I guess I would be more concerned with random shopping for additional fabric that is more of what I have or with out a purpose. I am trying to beat that habit this year. I can always use batting and thread. But I do not need any more pink, blue, green, purple, brown, yellow, orange or turquoise, you have the picture. I would pass on shopping for those. But for instance, if I had a planned project that required batiks and the shop had what I needed, I would shop. I don't have enough batiks to make a doll quilt. Tee-Hee-Hee. I would not be hesitant to shop to support my favorite LQS.
Just my opinion and not at all a judgement of others. If this episode of quarantine continues, I may change my mind just to keep a shop from closing. Until then keep sewing everyone and reduce your stash.
