DIY Mountain Triangle Wall Shelf

Turn this unfinished triangle wall shelf into a mountain masterpiece! A little paint and white cardstock paper will transform the shelf into a mountain. Take some black and white paint and mix into gray. Use a paint brush to paint the paint onto the shelf. Let dry. Next trace some white paper onto the top quarter of the shelf. Cut and make some jagged edges to look like snow on a mountain. Glue the paper onto the shelf. Makes a darling display on the wall.

DIY Faux Flowers Wood Triangle Wall Shelf

Add some pretty pastels with faux flowers to a wood triangle shelf for the prettiest display. We used a faux peony in blush and some faux eucalyptus. Trim the peony and adhere to the inside of the shelf with a hot glue gun. Add some little sprigs of faux eucalyptus using the hot glue gun. Wouldn't a group of these be so sweet for a baby or bridal shower?!

DIY Multi-Triangle Wood Shelf

This is one of our favorite ways to create a DIY wall shelf. We used 4 of the unfinished wood triangle shelves and adhered with strong glue (wood glue would be great as well). Allow to dry.

DIY Triangle Shelf with Washi Tape

Add some pops of color to the unfinished triangle wood shelf using one of our favorites - washi tape! First paint the triangle wood shelf white using craft paint. Allow to dry. We added a marbled coral and blue washi tape to the front of the triangle shelf. You can add as much or as little washi tape as you'd like! Make sure of press the tape onto the shelf firmly.
