First I trimmed off the other patterns from the same sheet. I folded the outside fabric in half, and pinned on the pattern for the front. Lining up the "grain line" line with the herringbone pattern, I cut around the line corresponding to the size (small, in my case) I need. (I gather this is pretty elementary so far...)
If you're right handed, cut around clockwise, and counter-clockwise for left-handers. There is a seam allowance built in, so don't worry about leaving extra outside the line. I made a blue X on the "wrong" side of the front fabric.
Now take out all the pins, set the outside pieces aside, and repeat the process for the interfacing, and the fleece lining.
