I don't own any, but I'd like to. It's a bit impractical for my household of 6 (plus guests) - we don't have the room to store a set of dishes that'll only be dug out once a year. I am a "Christmas Junkie" as my family would put it, but I haven't been able to convince myself to buy the Christmas china that I have been eyeing for 10 years now. No one in my family has picked up on my less than subtle hints that I would LOVE to get the Christmas china I've seen at the warehouse club! I've dropped the hint for 10 years now, and my totally clueless family hasn't got it! LOL!
I compromised by buying a set of inexpensive dishes that are trimmed with a simple border of red and green for our first Christmas Eve dinner party, and I can use them for other occasions as well. The problem with that is that while the number of guests have grown since our first Christmas Eve dinner, I have been unable to buy more of the same pattern because it's been discontinued.
My solution? I bought a set of inexpensive white china, and try to make it look like an eclectic, rather than mismatched, collection. When I'm setting the table, I alternate the red/green trimmed plates with the plain white ones.
To add Christmas flair, I use Christmas themed cloth napkins. On Dec. 1, I pull out our collection of Christmas mugs and display them in the kitchen. Theoretically, I put them back into storage at the end of the season, but I distinctly remember one year when it suddenly dawned on me in September that I was still drinking my tea from a Christmas mug!
No, I don't think it's impractical for you to buy a single place setting for yourself, if it is something that you will enjoy! So, go on, knock yourself out, get the prettiest Christmas china plate setting you can find and enjoy it for both of us!
