When I first starting sewing, I thought patterns were for pansies. Whenever I did use one, I figured I knew what I was doing, and didn't bother with the directions or envelope information. I was a dress size 6, but when I cut the pattern size 6 out, it was always too small. When I finally realized that pattern sizing is not the same as dress sizing, I still didn't use the right seam allowance, so then my pieces were always too big. The point I'm trying to make is that the directions and the information included with your sewing pattern are a HUGE deal. If you're not going to learn how to read and understand them, you're better off not using them in the first place. To save you from the disasters of my past, I'm here to teach you how to read a sewing pattern--specifically the envelope. You might be surprised to find out how much information there really is on the tiny paper packet.
