I have completed 2 so far. I am working on 1 and have another that’s ready to go once I finish this one. I am in the US. I don’t necessarily know the cheapest best ones to get. But I shop on Ali Express (more like window shop) a lot. Enjoy.

Iv done 3 so far an got another 4 to go haha! I love them ☺️ I’m in Australia but trying to find the cheapest best ones to get ☺️ x
