I haven't seen much for knitted bracelets per se (but I'm new so I haven't seen very much!
), but I did see & save one cool pattern for a small, lacy-looking wrist cuff that looks like a wide bracelet. It's got eyelets in the middle so you can string colorful ribbons through it to make it more dressy. The pattern is here
I'm also interested to see what bracelet patterns other people post! :D
