Hello John,

You can get chartreuse 3/8" foam cylinders at:

Stone River Outfitters
www.stoneriveroutfitters.com
1-800-331-8558

Part # M06326 (color), 6 pack, $1.75

These are the same foam cylinders I use for my Texas BullFrog, a former FAOL Fly-of-the-Week.

Hope this helps.

Cheers,

Richard in Plano TX
