We’ve just told you about cool triangle wall decor and today the project is about the same but the decor is dimensional. The supplies are paper (the thicker the better), a ruler, a stylus, a pencil, scissors, double-sided tape, a base for cutting. Draw a triangle of the size you prefer, and then draw another smaller triangle, using the same basis as above. Cut out the design with the stylus. Within the smaller triangle, draw two lines parallel to the base, with similar distances. Do not bother to measure because it does not have to be exact. With the help of the ruler, draw small triangle lines. Keep reading the instructions here.
