To add a bugle bead, you still stitch each bead on one at a time. Since it is difficult to achieve curved lines with bugle beads stitched with the holes against each other, it is easier to stitch them side by side.
Pick up a bugle bead and push it down against the Stiff Stuff. Pass down through the Stiff Stuff at the point where the thread exits the bead. Pass up again through the Stiff Stuff at the back of the bugle bead, then pass through the bugle bead again and down into the Stiff Stuff.
Making multiple thread passes through each bugle bead will make sure that if the sometimes sharp end of the bugle bead cuts one thread, it probably won't cut through all of them.
TIP: When working with bugle beads, sort them to remove any beads with obvious sharp or jagged edges before using them.
