This is my actual Christmas list that I sent to my parents. I've also asked for merino wool socks, isotoner leather driving gloves as well as a garlic press. All reasonably priced items that I need or would like to have. Nothing elaborate.
I find that sending online screen grabs of items is a really good system for people that don't necessarily know what you'd like. It also makes it really easy for them, and then you end up actually liking and fitting into what they give you. My sisters seemed to think it was cheating when I did this last year, but the jokes on them because I was super excited to get some of the items I asked for and while they were getting ill fitting sweaters and vanilla scented candles.
