Valentine's Button Tray

I've had this tray for awhile (I can never seem to pass up trays when I'm thrifting so I have quite a few) and finally decided to make it prettier. My button collection is still quite massive so I figured lining the inside with buttons was perfect. Currently I'm using this as a decoration but it will still work as a tray as well. If I poured resin in the tray the surface will be flat again, but I'm trying to control my spending and crafting only with what I have, so that will have to wait.
