Not that it’s terribly important, but I did it a couple of weeks ago, and it made me glad I never throw away leftover material. I had bought pipe insulation to make floaters for pots and a corral for floating plants in the pond a year or so ago. I had some left over, but didn’t toss it, and it was good that I didn’t because P had asked me what to get to replace the ratty, holey insulation that wasn’t “insulating” much at all, and after I’d finished, I had less than a foot of material left over. Perfect!
