Some people use a stapler to put a staple on the side of the hole that the wire pulls towards. Some just don't use anything. I think I've only met one or two people who actually use the eyelets. It requires a LOT of work.
The holes for the eyelets in the frames are 1/8" diameter.
Well you just met another who uses eyelets in frames for the support wire. HEHEHE
And I do know a beekeeper who had about 500 hives who eyelets in frames and yes he retire about three years ago.
