Browse any craft store and you will see rows of beads and jewelry making supplies to create your own jewelry. Even if I don't have a new project in mind, I always love to look at all of the beads and see what is new and what is on sale.
There are so many different colors, styles and kinds of beads to choose from. If I see some jewelry in a magazine or catalog that I really like, I love to buy materials to re-create that look. Many stores offer beading classes, and there are also many patterns online if you need some inspiration.
