This is not an original idea - saw it somewhere else. I found a roll of blue tickets at the thrift store. I covered the writing with matching paint.
(I suppose I could use gesso or white acrylic paint also.)
Then I cut tiny pieces of decorative napkins to fill in the rectangle space - I wanted to keep the numbers on the side so the pieces still retain their "ticket-ness." I cut words out of a book ("8,789 Words of Wisdom" - I used scraps that had already been cut up.)
I colored the words with Sharpies and Tombow markers - next time I will use watercolors for a more subtle effect.
These are fast and easy and I will add them to journal pages and happy mail. Just some silly little art.
