Wristwarmers are for you with aching wrists, and for you who like personal accessories. The idea is so simple that extensive instructions aren’t needed to get started. You need a thin wool yarn, I usually use Indicita Alpaca. You also need small glass breads that are large enough to be thread on the yarn. The first thing you need to do is to thread all beads onto the yarn, otherwise you will have to cut the yarn to thread on more beads later on. 
The easiest way is to take a sewing needle and sewing thread and make an eyelet. Lay the end of the yarn through the sewing thread eyelet. Thread the beads onto the needle and pull them over to the sewing thread that link over to the wool yarn. If you can’t guess what I'm trying to say, check my figure to the left.
Use rather thin knitting needles, around 2 mm. Cast on 30 or so stitches, depending of the length you would like for your wristwarmer. Knit every row pulling the beads forward on the yarn. 
On every second row, randomly drag a bead in place between the stitches while you are knitting. Bind of when the knit measures the circumference of the wrist and sew it together forming a cylinder.
Instead of adding the beads randomly, you can use a pattern for the insertions. Patterns are of course found in books, but you may as well make some yourself. 
Take a graft paper and get started!! You can also use ordinary cross stitch patterns, since the insertion of a bead follow the same rules as making a cross-stitch. One thing to remember is that the first pearl added on the needle is the last one on the knit. For multicolor patterns I recommend making a schedule in which order to add the beads before you start treading them on.
If you like to crochet you probably have some patterns for tablecloth that are built up by plenty of motif that look really good on their own. Crochet one motif adding a chain loop after the finishing, and you have a pretty ornament for the X-mas tree. 
I tried to crochet one motif in metallic yarn which made the motif a bit larger, and found that some of the beads I had at home fitted perfectly in the middle circle for some of the motifs. I also crochet plenty of white cotton motifs in different shapes to pin on our wine red living room curtains, representing snow stars that are said to all be different. That is also one way for me to use all of the patterns I have, I don't have any use for a dozen crochet mini place mats...
