My DH doesn't understand my quilting...cutting up perfectly good fabric into little bits to sew back together again??
But he has never said anything to make me stop and has been supportive in his own way.
Now that I have my own room (DD moved out 2 years ago) he will even bring in a cup of tea if I have been in there for a while and stop for a chat. I think after all the years he had his MAN SHED and was out there doing STUFF, he figures he doesn't need to understand it, he's just happy it makes me happy.
