What would make it perfect is a trap door or sliding bottom for easy emptying- An awesome DIY bottle opener, perfect for outdoor parties. It even collects the bottle caps. Ideal Father's Day gift or project to make with Dad.
I love you clothes pins: Write a message with a FINE POINT sharpie so it doesn't smear. Write "I love you" on a paper. Cut it out, and hot glue it to the clothes pin end. Would be cute for a care package!
