I painted the knobs to go with the 'trucks, cars, traffic' motif in the room. Each knob was $0.97, so it was an inexpensive way to add some personality to the room. I used acrylic and made the outlines with permanent black marker, and once dried I sprayed the knobs with a gloss varnish. It was tricky painting on them because of the uneven surface, so it took me a little longer than I thought. About 1.5 hours.
This is the desk portion of the furniture. It looks fantastic! My father in-law thought of every detail, the shelves are adjustable and the sides have a lip so there's no way for my son to pull them off. There's also a light right above the desk.
This is the bed with the shelves. Outstanding! The bed has drawers on both sides for storage and the drawers are so easy to open and close. All the shelves and drawers provide so much storage! There are lights above the headboard. The green stain on the wood really makes all these pieces more fun and great for a boy's room! My son was very happy with his gift from 'papu'.
