Leader Enders Quilt

I followed Bonnie Hunter's tip of using patchwork shapes as threadsavers so that apparently effortlessly you end up well on the way to a finished to[. The snag is, I find, is that the "thread savers", or leader enders as Bonnie calls them, become more alluring than the main project.
Anyway here are squares sewn into pairs then four patches - I undid the stitches in the seam allowance so that my seams went all the same way as described here. Then I could join the four patches into bigger four patches the same way again. 
The quilt is going to a friend who has gathered quite a number for a specific charity project.

All squares 36x45"
