Here's another cozy that I've made for my phone...
Pattern adapted from here:
See how cute it is!!!
I gave the flap a miss as it turned our weird. I put in a button instead, it's not pictured here as it was done after I took this photo. I also made some adjustments as I didn't understand the part about the decrease.
This turned out so cute that I couldn't resist making another one. A fuschia color one this time.
This time, I made the opening to be right at the bottom, and made some eyelets to create a drawstring pouch. Here's the closeup of the bottom part.
