Oh, thanks so much everyone!
Julie, I did pick up 52 stitches around one of the openings and added 8 rows of 2x2 ribbing with a sewn-in binding. It made the gap more noticeable. :( So I ripped it out... I wonder if picking up 48 that skipped the top of the opening would allow me to tighten it up. hmmmmm. What do you think?
Lilsea, I can do one row of stand-alone single crochet. Beyond that, I'm crochetarded.
five_six, I shall visit my favorite LYS at lunch today and see if the resident expert can hold my hand with that tweaking. I'm also looking for a sock monkey to stitch upon the front to match the baby's sock monkey slippers. Also, I'm adding a little duplicate stitch lettering to the seat, then lanolizing it.
gonna run outta time.
