Shirt Sew-Along

Today is Day 1 of the Men's Shirt Sew-Along. I have to admit I am a bit nervous about it all and I'm just hoping to have a shirt with only a few errors and it will fit well enough to actually be worn.
Here is the fabric I picked out. It's flannel shirting and when I touch it I just want to wrap myself up in it, which I hope bodes well for a cozy shirt. I am doing the pattern with muslin ie: vintage sheet, first to catch the mistakes I am bound to make, so hopefully by the time I get to the real fabric I have worked out any bugs!
Anybody else out there doing the shirt sew-along?
