My dogs are adorable, but for some reason they decided to chew on all 4 sides of my coffee table. I've always liked the idea of an ottoman coffee table, so I decided to make one myself. Most materials I got on sale, so my total project cost was $42. All it took was a staple gun and 2 hours. ... well, and all the supplies listed below. Listed are the dimensions of my table, but it's totally flexible.
1/2 inch plywood (28x48) - Have them cut it at the store. They usually do for free
fabric (36x56) - add a few inches to the side and top to your plywood measurement. I chose something transitional. An upholstery fabric is a good choice.
warm and natural batting (34x54) - trust me, this is the best batting and will stand up to a staple gun
staple gun + a bunch of staples
iron + ironing board
