I use more fabric from WalMart than JoAnns and Hancock put together I have never pre-washed and there hasn't been one shrink usually the only thing wrong with their fabs is it got off centered on the wrap at the mill -my W/M has a much better assortment of Batiks and 1/2 the price of Js or Hs and a free Quilt of the month pattern and the fabs to make them in. I had to make a dress JoAnns had a sale 50% --$15yd reg =$7.50-- a glass of 7-up spilled on fab -sticky-washed it I lost 6in on the lgt and 2 1/2 on wd in the washer I did not put it in the dryer this was PRE-Shrunk but in my case it was RE-Shrunk and no satisfaction from JoAnns so now I only buy thread at Js
