If a sewing machine is on your child's wish list, I have a few tips on purchasing a machine that will get them started.
Whatever you do, please, please don't purchase a "toy" machine. That will lead to frustration and sadness. I recently saw this one that is "threadless." It reminds me of a story Andria tells about having a sewing machine that used glue instead of thread when she was little. Fun, but ultimately a disappointment.
The main feature that I look for when purchasing machines for kids is a drop-in bobbin. I have found that this makes sewing soooooo much easier for kids.
You know I love the Janome Sew Mini (don't pay more than $50, it often goes on sale at Hancocks!), bur I realize that it's not the ideal machine for everyone. It's a good starter machine, but if your child is older or you would like to sew on it as well, purchase a full-sized machine.
Happy gift giving!
