For me, going to a quilt store is a treat. I LOVE to look at the colors, fabrics, get inspiration, and yes - buy something that keeps the business going and me happy. When it stops being fun (and it is not something I can fix) then I stop going. I may find an alternative (different store or different group) even if it means driving a bit further.
You say that money is tight, so maybe you are looking at the situation with a different filter. Maye it's time to further the skills you already have. Then you can show us and we will be your support. We won't make you use thangles.
