It was great being the guest judge for this week's episode of "Top Design." Being able to see the energy of the talented contestants and being among friends with great style and wit like Kelly, Margaret, Jonathan and Todd. It's always tough to agree on design. It's even tougher to take a bunch of competitive, talented designers, put them all together and expect them to pull off a design that really hangs together. The results for some were to do their own thing, while others struggled to work together and be true to the big idea. The hits for me were the inventive use of the space, particularly the stage area with reversible curtains and all the things the kids would need to put on a show. The color and the storage ideas fell short due to lack of time and not getting it all together. The best designer we saw had strong ideas, but not a huge ego. The ego got in the way for a few contestant. I'm really excited to see who finally wins. For Mark Rios' bio, click here.
