find your 1/4"!!!
cut two 3" squares, sew them together along one side, and press seam allowance to one side, measure, it should measure 5 1/2" if not adjust and try again, once you find your 1/4" mark it on the sewing machine (some people use masking tape, there's lots of 'stuff' on the market)
once you are sewing a consistant 1/4" your blocks will fit together easier.
good luck.
the trimming them all to match works, but sometimes you loose points doing it that way it's better to work on being more consistant.
