Not to take anything for the work she does, but I made a simple bead counter for the mo.com guys with 15 beads and a few for the northern guys with 20 beads, but in all honesty I would stick with the 15 and when it is full start over and quit at 10 more making 25, I done all of ours in 5 same color incurments making it easy to tell , like the red,white,blue , then restart and pull the red & white ones making 25, and sold over 600 at spring camp a few years ago for a buck each, lots of guys bought 2 to 5 of them......and they are only about 10" long and can be hanging from your pocket or clip on your shirt ............in fact I sent slab $300 from the sales to help the site........
