Oh, I forgot--

One hardish part about knitting the uterus was putting the pipe cleaners into the fallopian tubes (they're posable!). What I ended up doing was threading the pipe cleaner onto a yarn needle and threading it through the tube so there was pipe cleaner sticking out of both ends. I then took it off the needle, bent the end as called for in the pattern, and pulled on the end sticking out of the cast on end until there wasn't any pipe cleaner left sticking out of the loopy end.

Did that make any sense?
