 Take a 3/8 board a drill holes the size of your jar mouth. Place jars
over plugged super in heavy flow. We have tried with single piece of
foundation and just empty jar. They built comb in both leaving approx
3/8 bee space. We made about a dozen jars to use at our State Fair booth
. Filled with honey they were quite striking. Not hard to do with a
heavy honey flow.
