Sushifan, I did my first Thanksgiving a few years ago (after taking a new job and a severe paycut for my sanity ) I don't know if you have anytime at all but maybe over the next year or so you could try this for your next dinner or even this one. I like to junk hunt - go to thrift stores and I found ALL of my serving dishes at places like that. Beautiful pieces that while they didn't match "match" they did tye into my dishes and my kitchen. Boy did I have a ball hunting for the perfect bowl to serve mashed taters, or gravy boat. none of it cost more than a couple bucks a piece and my table was beautiful! You know Martha is always throwing together stuff that doesn't match, that is the new thang! Besides think of the stories you could have for each interesting and amazing piece you have collected.
Relax! somehow on Thanksgiving everything taste perfect when you are with people you love.
