For dark colored felt, you'll need a different kind of pen to make your tracings show up without bugging out your eyes. I've tried so many things-- chalk, crayons, etc. The best to date is the relatively new silver sharpies. Shows up on black and writes wet like a regular pen. However, they make your template wet around the edges, the ink "stinks," and the pens run out of ink quickly. Luckily, OfficeMax runs "buy two, get one free" specials on these!
Real sewing people use pins to hold pieces in place, but I like to glue the main body pieces together using Aleene's tacky glue. This stuff dries fast and clear and holds tightly. Also, when you make a mistake, you can rinse this glue right out. Not to mention that pins at the crack of dawn will inevitably lead to pricks and pain! I find it at fabric/craft stores and buy the BIG bottle with a store coupon..
