Here are some photos - and my version of instructions!
Behold - the half hour project that will have you pulling an Oprah - You get a pair of mittens, you get a pair of mittens and YOU GET A PAIR OF MITTENS!
Start out by cutting out your pieces.
Next up - put your back pieces together, and sew GOOD SIDE TO GOOD SIDE - just where the thumb is :) see the photo below
Then line up your front to your back, and sew them together! Be careful not to catch your thumb in the seam.
