I've made clothes pins in a plethora of assorted colors and styles...these are by far the easiest, and a great, super quick gift idea. You can grab a pack of 36 pins at the dollar store, and I've found the small stamps for a dollar, and the ink pads are 2 dollars on sale (you can also color the bottom of stamps with markers).
I stamped a bunch of fun little sayings onto the pins and pinned them to a card (saw this on pantinawhite). For 15 cents....a little gift for a teacher or friend in my life. It definitely fell within my budget and what a fun way to clip together papers/hang papers or even top gift packages.
