I'd like a tree like this and heart shapes cut out of paper. Guests can write their well-wishes for the couple on the hearts and attach to the tree with small clothespins. Later, the hearts could be put into an album or grouped together in a frame.
Pick your Picks holds your guitar picks without obscuring any portion of the plectrum, fits most styles and sizes of picks and is free standing or wall mountable. You can display the frame with covering glass making a great display piece, or without the glass to allow easy access and storage of your picks.
