Glass beads that are perfect for tying BMS patterns. Also useful for small midge and other flies where a slow sink rate is desired.
Fly tyers have figured out that little glass beads incorporated into size #12 to #24 flies really add to the attractiveness of the pattern. How did we ever get by with our midges and scuds and leeches were tied without metal or glass fly tying beads.
Many effective fly patterns call for a single bead at the head of the fly. Some innovative flies use a string of these beads to form the body of a fly. Let your imagination go wild. The glass diffuses light and refracts sparkle and attraction.
