Beading
The hobby begins with an understanding of how one strings individual beads on a necklace and creates knots between them. Have a look here for an example. There are other demonstration videos if you search for them. Then you'll need to find some beads to work with. Your local crafting store may be able to help there. Don't start out trying to make commercial quality works until you have your technique down. Finally, use the links here to find the styles of beads you desire and make your first piece. In time you will find youself making one-of-a-kind gifts for the holidays that will mean more to the recipients because you made them yourself.
