Secondhand ottoman + scavenged casters from old bed frame + scavenged round glass table top = Moveable Coffee Table!
My friend, Sylvie (she of exceptional taste and recent move) gave me this wonderful ottoman.
(Small watt light bulb goes on)
I rummaged through all the bits and pieces I have scavenged over the years (and have never thrown away - you never know....) and came up with four casters from an old iron bed frame that I recycled. I also had tucked away a round glass table top that I couldn't bear to part with, although the table fell apart long ago.
Out came the trusty Makita 18V cordless drill - quite luckily, the leg protectors, when pried off, provided a perfectly centered pilot hole for the drill.
