I prefer the look of hand sewing the back down. Mainly because it's not always easy to get it looking good on the back when you machine stitch it. I did recently glue baste the binding, then stitching it by machine. The first one was just ok. I adjusted the needle a bit and got it better on the next one. Last weekend I made a doll quilt for my granddaughter and forgot to move the needle over. I hated how it came out! But it was only a doll quilt, so I let it go. I forgot to make myself a note of what to use for the needle position, so I need to experiment and stick a note on my machine to remind me.
