I have made some blocks of the sawtooth star pattern for a quilt. I would like to add some extra size to the blocks and make them the Rising Star pattern (star in a star). Because I don't have a pattern and this is my first attempt, I need some assistance in calculating sizes for the additional Rising Star pieces. For the sawtooth stars, my center block is 4.5" square. Middle top and bottom (for the flying geese sides) is 4.5" x 2.5". Outer corners are 2.5" square.
I currently have four different fabrics for stars (same center and points on white) and have made eight of each star for a total of 32. Any suggestions or picture samples on how to put it together so it looks nice? I'm thinking some sashing in between the stars?
