New Year's Top

Let's hope. I traced the pattern and am ready to cut out. I want to finish this top to wear tomorrow night.
I've had this beautiful stretch velvet in my stash for a couple of year and never knew what to make of it. It is so pretty. The glitter parts are a copper color. The velvet is a deep black. I have no idea what it is made of and am not even going to prewash it!
I'm using the Silhouette's Pattern "Dana's Top" to do this one. I was surprised when tracing the pattern to find out that the sleeves are 2 piece. Well, they are two piece, but both pieces are identical. I may see if I can line these up with a fold and cut them as one, since I don't see the advantage of the 2 piece sleeve if they are identical. Let me know if I'm missing something here.
You can see there are some vertical and horizontal lines on the fabric, but they don't line up or continue all the way across the fabric. Sometimes they just stop and other lines are in different places. I'm not sure if I'm going to try to line anything up at all.
Wish me luck!
