Cardboard, duct tape & contact paper
Are helping me decide if I really want to do the 2-tier island... I know so many people are ripping out their 2nd tier, but I think I might really like this for organization and "protect the kitchen from misc. stuff" aspect. I wanted to live with it for a bit before doing the real thing -- much less $$ than deciding later I was wrong!
I put contact paper on it to make it at least a bit cleanable.
So far, I really like it... but it's only day 2. ;-)
