Sand the wooden blocks and paint them with antique white. Paint each block with thinned brown paint (or age with antiquing gel) and wipe off. Sand the edges of each block.
Use your a software program, like Word, to type "LOVE" in Papyrus font, size 82. Print out the document and size it against the blocks to make sure the font is the right size. Change the word "LOVE" to just the letter "L" and print it on the first paper. Repeat with each letter for each patterned paper.
Trace one of the wooden blocks onto a piece of scratch paper and cut out. Cut the square a bit smaller and place it onto a wood block for sizing purposes. There should be visible block all the way around the paper square. If there isn't, trim it. Using that square paper as your guide, cut out the patterned letters.
Decoupage each letter onto each block. Let dry.
