Cut your MDF wood to 2.5" x 4", or the size of your choice. Use a cutter to score the back and the front (along the same line). Once it is scored, you can snap it pretty easily.
[mv_schema_meta name=""]Sand the MDF wood tag and drill a hole on the top-center of the tag for the hanger. Place painter's tape on both sides before drilling so you don't split the wood. Remove the tape to sand.
Cut out the cardstock or scrapbook paper to fit the tag. Cut both a front and back. Apply a medium layer of Mod Podge to one side of the tag and smooth the paper down thoroughly. Repeat on the other side and let dry for 15 - 20 minutes.
On another wood tag, apply washi tape on both sides and trim with a craft knife.
Apply two layers of decoupage medium to the front and back of both tags to seal, and leave to dry (do one side and then the other).
If desired, add some liquid leaf on the edges of the tag to create a more finished look.
Tie on the twine or ribbon that you will use to secure the tag.
If desired, add decals or stickers to the tags (you can also add an address label).
