Paint your blocks. Allow the paint to dry completely.
Use the blocks as a guide and trace the block on the back side of the scrapbook paper. Cut along the lines so the scrapbook paper size matches the block. Repeat for each block.
Cover the back of the cut scrapbook paper with Mod Podge, place it on the face of the block, and press down. Allow the Mod Podge to dry completely. Repeat for each block.
Apply the sticker letters to the scrapbook paper on the block and brush the surface of everything with the Mod Podge. Repeat for each block. Allow the blocks to dry completely.
