As usual, though, I have some tips.
First - it you are doing Sedona Sky, you'll need to either get 1 inch more than the half yard called for, or you'll have to use some of the left over strip set fabric. Its doable, but if you don't want to worry about it, just get an additional inch or so.
Third - reduce your stitch length when you sew your strips together. Since you'll be subcutting these into 2 inch units, your stitches may unravel a bit, so its best to use a tighter stitch. I almost always do this for strip sets that will be subcut.
Forth - if you are making the Sedona Medallion, it uses the same amount of fabric as Sedona Sky.
Two down!
