You already read these Sewing School Rules in Lesson One. Here are the reasons behind them.
This is very important. Just like a grown-up’s needle, your needle is sharp and will hurt if it accidentally pokes someone. Never put a needle in your mouth! Take the time to make a needle book to keep in your sewing kit. If a needle does poke you, be sure to wash the spot with soap and water, and ask a grown-up to check you out.
Find a good place to sit and sew. This can be in your bedroom, a chair in the den, or an out-of-the-way spot in the kitchen. Wherever you go, don’t walk and sew! And be sure to check in with a grown-up whenever you need to use an iron, or when a project calls for adult help.
What you sew might not look like stuff you could buy in a store, but that’s okay, because you made it yourself. Most sewing mistakes are easy to fix. You can undo your stitches just like you can erase a line that you made with your pencil. Simply take off the needle, put it in your needle book, and carefully pull your thread loose; then start over. See Oops! Something Is Wrong! for more ideas about how to fix a project that’s gone wrong.
None of these projects have to be completed in a single day, or even a week or a month. Sewing is not a race, so try to relax. When you want to take a break, store your project in a plastic bag that zips closed.
