Normally small gaps between the edges of the follower board and the hive walls isn't a problem, but I"ve cut out the center of my follower and replaced it with plastic queen excluder material. since a gap would defeat the excluder function, I need to get a better fit.
Somewhere I saw mention of using screen mesh to get a good fit, but am having no luck Googling.
Anyone seen mention of using mesh and maybe point me to that reference? - Mike
