I do have some lumber left over from previous operations and some purchased recently that I was thinking to use in building some mini matting nucs.
Last year I used some models, 4 way half frames, Apidea, Man Lake and Bee Works.
I am trying to gain from any ones experience to come up with the best design size, shape, ventilation, top bar and so on.
Any suggestions will be appreciated.

Thank you Gilman
