First you will need some supplies:
thin sheet of balsa wood
white acrylic paint
sharpie paint markers
Step 1: Measure out 2" x 2" squares on your balsa wood and then cut each square in half.
I ended up with 16 triangles and only needed 11.
Step 2: Primer with 2 coats of white acrylic paint.
Step 3: Paint 2 to 3 coats of chalkboard paint. Let dry and then punch holes in each corner.
Step 4: Decorate edges with Sharpie markie.
Step 5: Use a needle and embroidery thread to weave in and out of the punched holes and buttons to connect.
Step 6: Write message.
Step 7: Hang and Enjoy!
