Techie Cozy's

This is my first crochet project this year, "the techie cozy". I told everyone in my family that my feelings would be hurt if they didn't use it. I am learning to crochet on Craftsy and I have so far learnt how to single, double and half crochet-next granny squares. I'm not sure if I have got the gauge right because I have been using old wool and a crochet hook I had lying around. The two camouflage cozy's are for the boys in the house and just have a chain loop over the top to hold the phone in. The turquoise one is of course for the girl and her one has a flap.
