Here are four of the blocks - very gutsy, as you'll surely agree!
I cut a strip about 1" wide, the length of the blocks, and placed it right side down on the edge of the blocks I was going to join together.
I sewed straight through the blocks and fabric strip.

Then I folded the strip over, turned in the edge, pinned and slip-stitched it. (It would have been even easier if I'd ironed the strip under down the free edge, but hindsight is a wonderful thing!). Since the blocks have been quilted right to the edge, it wasn't possible to trim the wadding, so the seams are a little bulky. Never mind, it'll just add to the snuggle factor!

Here are the two blocks from the front. Looking good. Now I'm off to watch the tv and sew the strips on the back!
