Just to tell you how small the sweet peach's feet are, I put the pattern to her, and the 12-18 month size was GINORMOUS! The 9-12 month size was HUGE. The 6-9 month seems slightly big, and the 3-6 looked like it would be a perfect fit. She's almost 14 months old y'all. I went ahead and made the 6-9 month size to give her room to grow. Plus her feet are really tall fat. Does that make sense? They aren't wide, and not really like fat. But they are tall. Fat. Well, that makes sense to me, and I was the one sewing, so that's the decision I stuck with. They are a little too big. She can rub her heel on the floor and the shoe slides right off. But for the most part, they work great. The sole isn't sewn in to this shoe. I really like the look of a sole, and so I keep trying to keep it in the shoe. My glue gun mysteriously doesn't work (AACK!), so for now, I just set the sole in the shoe each time she wears them. Other than that, I am SO pleased with the shoes! Sew on the vintage buttons I found in my Great-grandmother's sewing box, and you've got a recipe for success!
