I have nevr ued anything except yardage for making quilts but came across a pattern that I fell in love with that uses fat quarters. I am thinking hat would be 9x9 piecesut would like to be sure before I start anything. Really don't want to go out and buy more fsbric and would like to use from my stash so want to know that I can get the right size pieces out of my stash. Thanks for your help. Mary
