The Mary Jane pattern was pretty easy to follow. The only thing you have to remember is to reverse the cast on stitches for the strap so you don’t end up with two left shoes. Hey, if you can do beautiful work like I’ve seen you do, this should easy. These are knit flat so it won’t look right until it’s all seamed. If you occasionally bring the cast on edges together at the bottom sole as you’re knitting, you’ll see the shaping. Maybe that was why the pattern seemed “off” to you.
It’s easy to embellish these. Sew a running stitch on the top edge of a lace ribbon, gather it up. Sew it on top of the shoe and sew or hot glue a cute button on top of the lace. Do make sure it won’t come loose, though, as buttons can be a choking hazard for babies. I’m thinking like a large one-inch four-hole button in a hot pink color. You can do the button alone if you want. For a boy, blue booties with maybe a blue anchor or sailor type button. You could also use a novelty button shaped like an airplane. These are nice because the baby can’t kick them off.
