This one was really challenging. I think it was partly the intricate string and then I went with a fairly intricate main pattern, which left me struggling to find a suitable background/filler pattern. The KISS principle really applies at times like these! Simple circles and hatching were much better than the other pattern I started to use and managed to cover up.
Using string 009 from tanglepatterns.com and patterns pendrills, poke root, zinger. and keeko (sort of).
