I have completed one bootie and am halfway through the second one. I will update the pictures when they are both finished. They are size 12 months. Might not fit Aaron, but it's the largest size the pattern gave. I will give them to my nephew, Seth, if they don't fit.
Update: July 12 - I finished both booties. They are too small for Aaron, so I gave them to Seth and they fit him perfectly. I forgot to take a picture of both of them finished, but the 2nd was identical to the first, so you can imagine the pair :)
