YOU can make this! Select size of wood you want your 'trough' to be. Hammer sides together w/finish nails on outside ~ or, L-brackets on inside. Paint or stain. Fill w/pebbles, moss, colored glass, etc. Sink several cans of Sterno in your base & Voila! You have wonderful lighting-- can roast marshmallows or even S’mores! A great party idea!
Use a poster board, any kind of squared wood for bottom with edges and christmas lights. Cut any size holes in the posterboard . christmas lights sit on bottom of square. shape the poster board and use a thin line of hot glue to hold them together. Hmmm!
