I love the way you handled your friends husband. I have done that a time or two myself. But the one person I loved doing it to was my brother-in-law. He was telling his wife she was spending to much money and time on her quilting. I went off. Mainly because she had only spent $100 in a year on material. The rest of it had come from my stash. Also as for her spending time on her sewing it was to make gifts for her kids and grandkids for Christmas because he is a scrooge. LOL.
So needless to say he got a taste of me. Since then he hasn't said a thing when we go shopping for material or when we get together and quilt.
As for the problem I have with my husband and my quilting . Is he buys more material and things for my quilting than I do. LOL. My sewing room is small and he keeps loading it up with things. I now have to sew out at the kitchen table since I have no room in there for my machine and me. LOL
