If you want to use beads in your crochet work, there are different ways you can approach it.
You can string the beads onto your yarn or thread, and incorporate the beads into your fabric as you crochet. You can see many examples of this technique by browsing through the bead crochet patterns posted at Crochet.About.com.
Another approach: you can stitch or embroider the beads onto the project after you’re finished crocheting. An example of this approach would be this beaded choker, which is also posted at Crochet.About.com.
I recently posted an in-depth step-by-step tutorial for another approach to crocheting with beads. The tutorial is for how to crochet with beads and wire, and it includes a free napkin ring pattern. I think the napkin ring is timely right now, with the holiday season in full swing; we have Thanksgiving, Christmas, and New Year’s all coming up in the next several months.
If you’re planning on entertaining guests for any of the holidays, napkin rings are lovely little accents to have on hand for enhancing your holiday table decor.
If you celebrate Christmas, this page of Christmas beadwork patterns might also be of particular interest.
These are not the only possible approaches to bead crochet, but they are few of the most popular, and also a few of my favorites. You can find a few more ideas for crocheting with beads at About.com Crochet. I’ve enjoyed all of these approaches to crochet using beads, and I hope you will enjoy playing around with them too!
