I chose to use a plane cream fabric for the sashing and binding, and the seam ripper is out. I'd stitched that row together the wrong way round.
Its turned out to be quite a big quilt and in fact it measures approximately 80" x 64" which is much larger than I intended to make when I set out on the project, as I was thinking of making a lap quilt!
I love how the back turned out too.
Now it's finished I just need to get it to the local Project Linus rep for re-homing.
