That's a tough questions, a lot of young people I know these days seem to be minimalist and aren't sentimental so I'm not sure I would give something home made. It's also hard to guess what colors to use. The only thing I can think of is a table mat and placemats in either a holiday theme or either a neutral palette or black and white. I would definitely include a label on whatever you make so they at least know it was done with love and care.
