I'd always bought what I'd rather call 'what I like' than 'just because'...that was bad enough!!
Then I got a job managing the quilt fabric dept of a large craft store. The notifications would come thru weekly on what fabrics were discontinued/written off and I was to dramatically discount and move them. So I'd buy minimum 2 metres of each, some the whole card. The trunk of my car would be dragging on the road home.
Surfice to say, I was a favourite with my customers because I discounted 90%. And I have a ridiculously HUGE stash!!!
