Great gift for physics geeks and all physics teachers and scientists. It can be made with their favourite colours, I’m sure they’ll be delighted to use this hand-made, unique and known-only-to-selected phone cozy! Make your friend’s fellow-workers jealous and knit your own Doppler Effect Cozy today :D

It is simple and easy to make. You can knit the fabric on single-pointed needles and then sew it, or you can use double-pointed needles or circular needles and knit in the round.

I’m sorry guys, but pattern is no longer avaliable.
