I do alot of thrift / used / vintage shopping. I guess the issue for me is because I sew alot of my own clothes I know how much effort has gone into the construction of something, therefore I just can't bring myself to spend $50 on a skirt that I know took maybe 30min - 1 hr to make, especially when I could make myself 2-5 almost exactly the same for the same price (including the pattern)
My latest sewing project is a 1920's evening dress & coat for a friends theme party
