My DH spends a MINIMUM of 500.00 a month on his hobbies. I don't even ask for his opinion about purchases for my hobby and I certainly won't be turning my hobby into a cash cow.
I wouldn't confront him out of the blue and blindside him with your feelings. However, the next time he brings it up, say exactly what you told us. Tell him to think about what you've said while he is cooking dinner because you have to keep practicing your quilting.
