[VFB] Bead question

[Ken, Carolyn, Alex and Hershel]

Hello...   Here's a problem I hope someone may have some suggestions on.   I recently bought some plastic beads at a craft store --  orange and pink and red ones -- the shiny kind kids use for making necklaces etc -- I thought they'd be great for tying egg sucking leeches because I wouldn't have to wind orange or pink chenile on the front of the hook -- I could just slip a bead on -- not only would they look great, but they'd save me some time and effort too.   However, when I got home I found out that the hole in the bead was too big -- they slid right over the hook eye.   I'm looking for suggestions on how to keep them from sliding over the hook eye -- something simple and not time consuming -- otherwise I might just as well go back to winding chenile on the head instead of beads.  I can go to a fly shop and buy metal beads especially made for tying egg sucking leeches -- but they are expensive too.  I thought by buying the plastic ones I'd save tons of money in the long run.   Thanks for any suggestions.   Ken MacGillivray Coquitlam BC
