I have built a couple of 1/144 scale dollhouses from laser cut kits. The wood in those is very thin and the bits left over after removing the house parts can be used for various miniature projects. One of the things I have made using them is a trunk that fits several scales.
This is the trunk before painting. The black parts are cardstock, the lid is made of foamcore, the strips around the lid are leftover dollhouse skirting, and the rest of the wooden parts are from the dollhouse kits.
Here is the finished trunk with gold paint, some plastic decorations and a coat of sealer to keep the decorations secure.
