Progress on first pattern!

I'm really happy about the progress I am making on my bell-sleeved top! I've never been able to find a pattern I liked that was in my size (most sizes stop at large, and I'm an x-large), so I decided to try to make my own by modeling off of a shirt that I really like. The plan is to make it in 4 pieces and sew them together: front, back, and two arms. I started shaping the arms today. I've been writing it all down so I'll have the pattern when I am done. I'm so excited! It's going rather quickly. The only problem is something is wrong with my right shoulder, so I can never crochet for a very long time all at once. I'm planning on going into the doctor on Saturday...
