Squaring up my quilting fabric is not normally that important to me. The pieces are so small, that it usually doesn't matter. The exception is fabric with stripes....can't stand stripes that aren't straight....and panels. And I just wonder why ALL panels are printed crooked on the fabric? Even then, I only pull it enough to get the printing as straight as I can. The old saying, "Don't sweat the small stuff and everything is small stuff", applies to my approach of squaring fabric.
