oh man..........
I don't mean to discourage or depress you, but I have spent the last couple of days packaging and pricing thousands of dollars of quilting fabric for a yard sale. Wanna buy $50 worth of quilt fabric for $2? Come to Burlington, WI next weekend. My friend, Dianne, was a fabric stasher. When she died of breast cancer a year ago, she left a HUGE amount of fabric and half-finished projects. Sorting through all of it and finishing some of it was something I am uniquely qualified to do - there really isn't anyone else to do it!
Dealing with this over the past year has really changed my heart about stashing fabric (or hoarding anything at all.)
If you have money to spend on fabric now, but it into a good mutual fund (12% is a decent and not unattainable rate of return). Then you can go shopping after you retire.
