...what's been working for me (suggested by michael bush), are popsicle sticks glued (or waxed) into a grooved top bar (the long way, all the way across). i use the walmart "jumbo" popsicle sticks from the craft dept. ...just make sure to glue them all the way across the top bar...easiest to do before assembling the frame. deknow -- Adony Melathopoulos <[log in to unmask]> wrote: I will lay a bead of wax along the top bar, like Dee suggested. -- Visit www.honeybeeworld.com/bee-l for rules, FAQ and other info ---
