What are some good "filler" PWPs?

[pandaninjarawr]

I'm thinking of doing some extreme time traveling after I get the PWP's I want, and then time traveling to have my villagers leave places I don't want them to be at, and then filling it in with some filler PWPs to destroy later and rebuild. I was thinking of using the cut-out face board things and the custom design signs because they're quite cheap, but they don't take up too much space. Are there any other suggestions? :O

Thanks guys!

I had fire hydrants all over my town. They're not very big, but they are cheap.
