Last year I made these blocks based on Elizabeth's (from Oh Fransson) "Map of the States" blocks, but used a quick stack and slash method instead (you can find Elizabeth's original tutorial here and my tutorial here). Both methods have their advantages and limitations as described on this post.
I finally got around to adding sashing in Kona Cotton Snow, and I love how it frames the blocks. At first I was going to alternate the pink/orange and grey/green blocks, but then I thought I'd try having all of the pinky ones on one side and the green ones on the other. I liked it, but also liked the interplay between the different blocks, so I settled on this arrangement, and I'm really pleased with it.
This is a pretty big quilt for me (approx 57" x 83" - 145cm x 210cm), so I'm looking forward to seeing how it fits under my new sewing machine. I'm thinking about straight line quilting in the sashing, and free motion stitching on the blocks.
Now I just have to peice the back (not my favourite part) and then get down on the floor to baste it (not sure if I'll be able to get up off the floor once I'm down! - anyone want to come to a basting party??).
Addit: the blocks are 10" finished, sashing 3" finished and borders 4" finished.
Blocks are a combination of Hope Valley by Denyse Schmidt and coordinating solids.
As mentioned, sashing and borders are in Kona Cotton Snow.
