Just a simple, crafty tip for an easy 10 minute banner. Make a simple phrase with black watercolor on the back of old business cards. I know it doesn’t seem possible but the lettering looks even better if you kind of rush through it and get kind of sloppy. While they’re drying, color just the top half of clothespins with sharpies in rainbow colors (I always like the mini ones) and hang it up on some string. Together it took only about 20 minutes to make. Perfect to throw together when you really really meant to put up decorations earlier that day and the birthday boy or girl is on their way home from work or school! Eeek!
