Paint your base color. Then use blue painters tape to create zebra stripes. Tear the tape randomly to look like stripes. Paint your last color. After almost dry pull tape off and spray with clear. I even used a can of silver glitter to add a little sparkle. $10 project to change the look of a shelf I've had for 20 years.
Why do we ignore DOORS and CEILINGS? They are often so boring...they are truly just empty canvases! Upholstered doors are way out there and phenom, but at least, we could play with a complimentary paint color or an amazing doorknob! I am going to think about creating a knock-out door in my home!
