Thanks for this thread. It was very informative.
I thought to build my own mold but a friend found these online for much less (time/money) than I could build an untested one for.
I'll update this as the growing occurs.
I bought the cube one and the heart one. Here was the heart 10 days ago when I put the pumpkin in:
and here it was yesterday
Apparently I need to find a pumpkin whose destiny is _exactly_ the volume of the mold.
I put the cube mold around a fruit that aborted, so I just took it off and put it around another fruit. There's a lotta screws on these things!
If I can find it, I might try my old home-made mold as well.
This is much harder than it looks!
