Press the back of the sheet onto/into the space your covering, then use the indentations on the backing as a cutting giude. Just peel and stick! Cut into as large of sections as you can manage. It doesn't have to be exact; the excess can be trimmed once it's applied. Start with the bottoms of the compartments first. Then the sides. Use a thin, strong straight edge to stuff the edges into corners (I used a metal ruler for this). It's really easy. ---j
