What I do to figure things out before I start...
Been too many times that I though, "Oh, I have enough to do that." and didn't. I figure up exactly how to make it and exactly what fabric I need. I haven't done the stars yet to figure out cutting of the FQ set but EQ7 says it needs 2 1/4 yds of the colors for the stars with the colored center and the set has 10 FQs so that should be enough but can't be sure until I actually figure up how to cut them.
