I bought a roll of aluminum flashing at Home Depot and a pack of grease pencils (also known as china pens) for $17. I think I can use a pizza cutter to cut them to size. I was really impressed when I noticed the daylilies came with those wonderful labels. By the way, I have my own staff, got 8 of my own and feed a small colony of ferals (most of mine were stolen from the feral colony as kittens). They all love having me outside working in the beds.
