Lovely quilt, bright and colorful, just my style!
FYI: When making triangle blocks with 10" squares, put two squares good side to good side and then sew a 1/4 inch seam pm all four sides of the square. Then cut the x on the square. When you are done cutting, you'll have exactly what you need to make the hourglass blocks.
I go a step further. I cut 10" strips, sew them together on both long edges. Then I cut the sewn together strips into 10" squares. Half of the sewing is done! Now sew the remaining open edges of the 10 inch squares. When done sewing, "x-cut"cut each 10 " square.
