Thank you. That's what I was doing but following these directions and adding the 3/8 and 1/2 to trim. Which obviously isn't working out very well for me!!

Step 1Calculate the sizes of the sky and geese fabric for our 2"x4" finished unit.
Sky Fabric: 2" finished plus 7/8" equals 2-7/8"
Geese Fabric: 4" finished plus 1-1/4" equals 5-1/4"
Then cut 4 'sky' patches and 1 'geese' patch.
Personally, I like to cut my patches over-sized to start with, stitch the units and then trim them to the unfinished size. I find that adding 3/8" to the sky squares and 1/2" to the large Geese square provides plenty of 'fudge factor'. So I have cut the sky patches 2-7/8" + 3/8" or 3-1/4" and the Geese square 5-1/4" + 1/2" or 5-3/4" square.
