Take your glasses off... then you won't notice if a few are a little shorter
I know it's hard isn't it to get the consistency we want. BUT if you take a look at the old time quilts... you either have super stitches on quilts that are essentially whole cloth with some appliqué.... OR you have huge toe nail catcher stitches on utility quilts..... I think we are way too hard on ourselves.... unless of course you are hoping to produce show stopper quilts.
