In looking at the template, I think the four sections could be strip sewn and then each set cut out from the strips. Of course, you would have to be very accurate. Not sure I could do it.

If you have the EQ8 program you could make a mock up of the block and it will then tell you how much of each fabric you need. I like using this program on blocks I'm changing the size on or making it into a paper pieced block though this one already is.
