This is basically the same method as leaving the square whole, drawing a diagonal line, sewing on either side of the line, then cutting on the line. In the F&P directions, they just tell you to cut on the line first. There are no extra steps, you just cut first then sew as opposed to sew first then cut.
When you need HST, and you are going to start out with squares that will be cut on the diagonal, you add 7/8" to the finished measurement. So to verify LyndaOH's math, a finished 5 1/2" HST (raw 6") would need a square that is cut at 5 1/2" + 7/8" which equals 6 3/8".
So basically cut the squares at 6 1/2".
Pair up the colors as the pattern tells you & make your HST
Then trim them down to 6". They will finish at 5.5".
