Here is the YouTube to see how it was made:
Making this plant from Little Shop of Horrors has been on my list for a while now. I love how it turned out. The video shows sort of my process. Obviously should have taken more pictures to better describe but hopefully it gives you the idea. Go make one!
UPDATE!!! Many of you have asked some great questions on my YouTube tutorial of this. When I was building it, I never intended to make a step by step video. But turns out many of you want to make your own and now I wish I gave you better details of my process. I've tried to answer your questions but I think some more pictures might be even better. So I'll post them here and hopefully that helps. Basically, I didn't know what I was doing and solved my problems on the fly. My advice is get started and you'll likely do the same. But I hope this helps. Have fun!
