Itty Bitty Bugle Beads

Just on a lark, I ordered some bugle beads.  I'm not good at judging the size of things, particularly when length is described in the metric system, but I ordered #1's, which turned out to be about 3mm long.  They're itty bitty little things, and I can see a great application in bead embroidery.  They'll provide good coverage and detail at the same time.  I can also see their application as an interesting element in the Ndebele stitch.  C'mon in and check them out.  How would you use itty bitty bugle beads?
