So I got the new nano for my birthday in October and found out that no one makes cases for this model yet :( So like any crafty girl I took matters in to my own hands..
Before we get a move on with this, I wanted to let you know that this version is a little bigger than my first one. I wanted to solve the problem of storing the earbuds inside the pouch.
So it's just a matter of preference. For larger go with the 1/2 inch measurement, for the smaller the 1/4 inch.
If you are making this without the aid of an iPod the 3g measurements are as follows-
Screen- 1.25" H x 1.75" W
Wheel - 1.10 x 1.10 (I noticed that if I placed a quarter flat and traced around it with the pencil straight up and down it was the right size if that makes it easier :) )
