If you're going to do embroidery for other people and a lot of different things, I think you'd be much happier with a full set of colors. They do have different size sets you can choose from. Bobbin thread always stays the same. One tip I've learned and I did it from the start, use a good stabilizer, not that expensive and well worth the money. You can really tell the difference in a piece when someone doesn't. I don't like the look of all those puckers around the design. It will be interesting and fun to see some of your creations.
