Sleeves. . . .

I'm knitting like a maniac trying to finish the sleeves for my ribbon sweater by this weekend. My LYS is going to start having "finishing night" on the last day (or Sunday?) of every month and I figured if I could get these sleeves done I could get some help putting it together. I have never done set in sleeves before, so I hope it is pretty straightforward and I don't have to fudge too much. I want my first garment for myself to turn out nice! I only have about 3 inches even and then the decrease shaping to do. . . maybe by bedtime tonight? *crosses fingers*
