I used 3 different threads: white polyester, shiny rainbow embroidery, and neon green polyester.

I started with the white thread. It came out completely unremarkable.i was just getting the feel of how my machine handled it.

Next I used the embroidery thread. I bought it years ago to use on a mask for the pandemic and never got the chance. I'm glad I didn't because it's garbage! It looks beautiful but it broke on me several times and I was only able to get a small section to actually sew onto the yarn.

Last I used the neon green thread on a piece of felt. I bought this color just for fun and have been dying for an excuse to use it! I will definitely be making something using this color now!
