Garage Haunt wall ideas

[The Forsaken Crypt]

Hi, I have posted questions about walls before but I really need some help. Our theme this year is a haunted mansion and I was going for a rotting wooden slat wall look. We considered pallets for we have the time to assemble them but I wanted to know if there are some alternatives that look nice and are easy to take down and store. Any suggestions would be appriciated. This will be held in a garage
