Do not trim them down. Just make them fit, match the seams and stretch. When you quilt it it will all work out. This is assuming they are all cut to the correct size before you start piecing. What I found that helped is working on that quarter inch seam and being consistent. Oh yes, press, do not iron. Before cutting out pieces, I also iron the fabric on hot after spraying with Magic or starch. This will take care of any shrinkage.
