I don't really have a budget but about 4 or 5 years ago I went for 1-1/2 years without entering a fabric shop (too much temptation). During that time I was able to pay off everything I owed include the house (which granted is small). I'm retired so my money comes in on the first and I first pay any bills including the one credit card I use online. After they are all paid off I set aside what I think groceries, hair cut, cat hair cut, whatever I think I'm going to need for the month then anything left I can spend on fabric or quilting "stuff". It works for me. It was very hard not to go to the quilt store for a while but it was worth every minute of it. During that time I got reintroduced to my stash and used up quite a bit of it but there is way more to go.
I like to fish too so I can't use that one. I do handwork on the boat sometimes if its not too windy.
