Call me Peg Bundy

The wall above my sink is damaged. I need to cover up the imperfections in the drywall and I was thinking about using a glass tiles or a metal tile. I've never used either before so it'd be a learning process for me. I really love the glass mosaic tiles. I always see them being used on those home shows on television and they always look so nice. The home shows always make everything look so easy though. I don't want to spend the money buying the supplies and then mess it up. I wish I had a Bob Vila gene! I have a "Peg Bundy, Married with Children" gene. There are some things I am just useless for and home repair and home updating is one of them.
