4) Flaps are then cut into the topside of each carton, i.e. the side with the largest surface area and with the label saying “Humboldt Creamery”, etc. The same method is used as for cutting the migrations holes. Poke one hole in each corner of the top side of the carton, but cut along only three of the four connecting holes to make a flap instead of a rectangular hole.
5) The two cartons can now be connected with duct tape. Tape the top and bottom of the cartons together lengthwise on both sides. If using cartons with flap dispensers instead of screw top spouts tape those shut as well.
6) Finally, use more duct tape to make tabs for the worm bin’s flaps.
