I hand stitched the knitted portion to the cotton backing after very carefully measuring and pinning all around. The stockinette still wanted to roll even after being blocked and stitched to the backing. I think the front and back look really cute together.
Of course, I just had to have the satin lining around the edges. After all, the best blankies have that oh so smooth satin to nuzzle against when almost asleep. It also solved the rolling stockinette issue. This was my first attempt at mitered corners and they were much easier than I thought they would be. The satin border was a bit tricky- especially with my inability to sew a straight line. Each side had to be ripped and resewn at least once (did I mention that my darling daughter managed to break my seam ripper the day before? Unpicking seams by hand is no fun). The satin also seemed to catch on any rough edge of fingernail no matter how minuscule. My sewing machine, of course, gave me it's own problems with all the broken threads and running out of bobbin thread and all, but it got the job done.
I am very pleased with the finished result. I think it looks fabulous, the yarn was great to work with (it did go through the washer and dryer twice and got softer but did not pill or shrink) and the parents loved it. That being said, I really do not see myself attempting this one again. I think it took as long to do the finishing (seaming, backing, edging) as it did to knit the squares....at least it felt like it.
