The art of sewing is a very simple one to learn, so simple that you can learn and then teach your children. I highly recommend instructing all of your children, girls and boys, in the proper usage of a needle and thread because at some point they will have a snag in their socks or a rip in their jeans. If they know how to sew, they can easily remedy the disrepair. Go through the basic steps of threading a needle (not as easy as it may seem), basic stitches (mainly the running stitch), and the numerous uses for sewing.
A final note: Your seam ripper is your friend. It is no fun to rip out stitches and re-do them, but you will thank yourself in the long run when the finished project looks 10 times better. Don't be afraid to start over and backtrack. Take it slow, and make sure you read the directions very carefully. Also, most patterns require a bit of common sense (or not so common, depending on the pattern.) Read the instructions and try until you figure out what works. Most things don't sound like they should work when they are explained out loud, but once you follow the directions, everything tends to work itself out beautifully.
