When harvesting, place the filled frame on a table, insert the corner of a hive tool in the end foundation slot, twist, and lift off the frame half. Turn the sections flat on the table and lift off the other frame half. When enough supers have been emptied, separate each section from the sheet of foundation, and trim excess foundation with a small knife. Arrange rows of sections, place covers on one side, turn over all sections, and place the other cover. The sections may be labeled at this time, or better, just before being sold, as some buyers want them unlabeled, or with their own special label. In any case, if you are in a wax moth area (and most of us are), seal the covered sections in plastic bags, freeze at 0 degrees F, and be sure to let the sections warm up to room temperature before opening the sealed bag.
