Unlike traditional paper marbling methods, all you need is paint, cardboard and a few seconds to get this modern, organic rainbow effect—we used the technique to create a whole sheet of colorful stickers. Make a batch of these, and use them to seal envelopes, decorate packages, (hello, happy mail!) or festoon favor bags.  

Materials needed: Printable labels, gouache or acrylic paints, cardboard scrap with straight edge, favor bags or envelopes

Step 1: In the top right corner of a sheet of labels, squeeze several dots and lines of paint.

Step 2: Using the cardboard scrap, scrape paint down the length of the label sheet.

Step 3: Use excess paint on cardboard to paint another section of the label sheet. If necessary, reapply paint using the same technique to cover the whole label sheet.

Step 4: Use labels to seal envelopes or decorate favor bags.
