This was the coffee table at the beginning.
We started off by cutting foam for the cushion part of the ottoman. We added some material around the side of the coffee table. All of which was attached with spray adhesive.
Next, we stapled some cheap white material around the cushion so we could contain all of the cushioning. The material for the outside of the ottoman is outdoor canvas. This material only cost $13 a yard. You just pull the material up the side of the table really tight, then take a staple gun to staple it to the bottom.
You have to cut the material where the legs insert. (This is just depending on what type of table you are using to make an ottoman.)
Lastly, we stained the legs of the coffee table a dark brown. Of course I had to sand off the old paint first. Just dip an old rag into the stain then wipe WITH the grain. I think it looks better than painting the legs.
Put it all back together and BAM! You have a ottoman!
