This pic was found on pinterest with no good link: SO lets make our own instructions.

Cut a mouse head shape into a cork board, card board, or foam core board. Cut a piece of black fabric or burlap into the same shape a little larger so you can wrap it around the edges. You’ll have to snip here and there around those bends and corners. Attach on the back side with hot glue or staples. Add a ribbon and cute label if desired, as shown. Start pinning those Disney collectibles on. Attach a soda tab on the back with hot glue for hanging!

Scout leaders: this could also work for a meeting activity. Make a different fun shape and add all those scout fun badges
