Had an idea that I'm trying out: Took a postcard (4x6") piece of watercolour cardstock and drew a dotted line down the middle. I added dotted lines to corners and circle marks mimicking a tag. Afterwards, I'll paint & add stamping etc and hole punch the circles. Recipient would cut the card along dotted lines & tie ribbons to the holes. Now a postcard becomes TWO bookmarks! I may propose this to my son's teacher as a class craft project. Parents can help mail them out to relatives.
