Wow, welcome and grats to you for all those T-shirt quilts. They are such nice mementos, but are a special skill set and I avoid making them if I can.
Grats as well to a long arm, I have a small house and would have to give up any pretense of a normal life and have the long arm in the living room and just live in a quilting studio instead of a house. Hubby is supportive of me should I happen on a good deal, but so far I've resisted. Unfortunately my unquilted tops stack is getting huge and maybe time is coming... Originally I figured when my son moved out, I'd put the long arm in the family room but instead I got a husband and his computer desk. Usually the hubby is a better deal than the long arm...
