I'm just a bit too wide too fit a lampshade over my hips, so I built the spool out of multiple sheets of cardboard, tape and hot glue. The thread is yarn, and the needle is made from aluminum foil.
This needle and thread costume would be easy to finish in an afternoon. I think it look me 4-5 hours from start to finish, but yours should go even faster since I already made all the mistakes for you! WOOHOO
(big thanks to audreyobscura for taking the final costume photos and editing them! she's the best! xo)
