I guess I am very fortunate also. I have a good stash, I have been a sew-a holic all my life and got into patchwork and quilting in the early 80's.
My DH just shakes his head and says he doesn't want to know!!! I once complained that I didn't have a particular colour and his answer was.......Rubish! you would have every colour there is plus five that haven't been invented!!!
I live in the country and having a good stash has the advantage of not having to go to town especially to buy a particular piece of fabric. I mostly work in my sewing room at night and the local quilt shop is not open in the wee hours.
My DH is also very good at waiting in the car outside Quilt shops. Luckily for me he enjoys reading the newspaper.
