Here you go. This graphic is for a 12" block but you can adjust it.
ADJUST your cuts as follows:
Plain squares at 4" sq.
Star points at a GENEROUS 2.25" (or 2 & 3/8" if you're willing to).
Trim the finished block to 10 1/2 inches, being careful to allow same amount of float for the points around the whole block. It will probably be very close to this measurement anyway if you have used accurate 1/4" seams.
