"Oh Tannenbaum!"

I constructed these bug hotels from a couple of old, forgotted building blocks stored in the garage. I placed them on the garden pine in Christmas morning, 2020. Now, they are waiting for the residents to move in next spring :)

Work in progress, assembled, yet undrilled blocks (above) and below, the installed insect shelters later that day (click on image to enlarge)
