Inspired by an old post in 2nd gen forum: http://priuschat.com/forums/gen-ii-prius-modifications/40565-inexpensive-option-cargo-area-mat.html I made cheap cargo mat for my 2010 Prius using $15 3x5 floor mat from Lowes (item #261482). Pictures below show before (and the mat from store), making paper template, and after.
