Sewing pro-tip 1: Lining fabric is usually very thin and doesn't like my serger.

Sewing pro-tip 2: When sewing in a lining, don't assume you can sew it to the armscye and still be able to turn it if the shoulder seams are already sewn.

Or the short version, I like to line stuff that I make cause it hides all the seams and looks nice, but I am by no means awesome at lining things.
