You're not alone! :mrgreen: I've been sewing since I was about nine and I didn't know any of this stuff until the last few years, when I started collecting vintage sewing machines.
Thank God for the internet. If you're having a problem, you can put your symptoms into a search engine and a kajillion sites will tell you what might be wrong.
If you're having trouble getting tomatoes to set fruit in Texas in the summer or you can't get the nose on your baby doll sculpt to look like a baby or you can't find a certain kind of scrapbook paper or fabric, you just go on line and you'll find more info than you need. :)
