Very, very cute! And, thanks for posting the pattern link. I like the modifications that you made because it makes it look more finished (although I don't get what ch st 4 means...how it works, really).
Sorry about the fuzzy directions. Basically after you finish the body you slip stitch into the first chain stitch at the bottom of the body (the first ch st of the project). Chain 4 then single stitch into the next chain stitch on the body (repeat until you get all the way back to the first chain stitch). Slipstitch into the first chain stitch on the body. Finish off by tucking in the loose yarn.
Does that make sense?
I just tried to quickly explain and did a poor job, LOL.
It makes perfect sense! I thought it might be something like that, but I wasn't sure if there was a new technique I needed to learn. Thanks for explaining
