Do additional players have their own custom design slots?

[CowKing]

I'm asking because I'm thinking of making another character just for more custom design slots (and because I want some tents for my camping area) but I heard someone say that everyone shares the same custom designs, is this true? Cause if so, that's just horrible, there's not enough slots for the stuff I wanna do
