Need a disposable drop cloth for a project? Buy a new shower curtain liner and use your old one as a drop cloth before tossing instead of buying a single use plastic drop cloth.

A heavy duty (2-3 mil thick) 9'x12' drop cloth at the hardware store is about the same price +/- $1 as a shower curtain liner from a store like Target or Fred Meyer (aka Kroger). A shower curtain liner is smaller than 9'x12', but if it's big enough to suit your needs you can get a new liner and reduce your use of single use plastics for about the same cost as a single use drop cloth.
