My Hubster understands that quilting is my mental health. At first he would get a bit frustrated that I gave all my quilts away, and he still feels I should buy fabric for two so I can give one and sell one. But, he has become well versed in quilt lingo and quite often will point out things in other peoples quilts that I wouldn't have even noticed. He is my biggest fan! He is totally supportive within reason of expenses too. I too am blessed.
Here is hoping that after awhile your Hubster will see how important it is to you and, not neccessarily understand, but accept your addiction...I mean, hobby!
