I think there was some problems that some people were having when turning and stuffing the the fingers on the Elenore doll. One of the problems was the seams popping. I have the same problem occasionally. If you stuff them with the pipe cleaners, and then either do a ladder stitch to close it up, or an overcast or whip stitch, it doesn't really show all that badly as long as you're using the same color of thread as your fabric. None of us is perfect.
Do you use the pipe cleaner as is or folded in half with the not sharp end out?
I went through 3 right arms on Spock before getting it to look right and just want to know how y'all do it.
