No, I do not know what dh has made-up behind his machine; hard to tell because he invents things that work for him. He helps me cut out pieces for quilts because he has two eyes, and I have one that sees. I just turn my blind eye toward the worse mess.
He also makes his own kilts to wear since we retired 'cause the others on internet is too expensive.
I have spend a number of years building up my stash before we retired...in Corpus Christi and the four LQS there. DH said, its your choice when we move to retire: all your kitchen food stuff or your sewing stash. You can see what my choice was.
Here in retirement in North Central Missouri, I have a new friend who loves to quilt, has a stash much bigger than mine, and is willing to take me along on her once a year road trips to acquire new materials. She also knows more about quilting than I do, and is willing to teach me. (She loves my home cooking)
