Here's another homemade gift I've made with my mom for a previous Christmas: graph paper notecards. This is basically the easiest homemade gift ever, but it's great because it can be customized in a million ways to suit your recipient.
You can play around with different words and colors ...
... or different fonts and monograms ...
... or make a personalized stack in one color/font or many ... possibilities are endless!
Easy and cute packaging suggestion: a bit of ribbon and a sharpie (who doesn't love a sharpie?!).
These are a great little gift for a teacher, co-worker, or hostess, and they're quite economical: 100 notecards cost me about $2.50, and you could do a few sets with that (just want a respectable looking stack thickness...). You can buy sharpies individually at some places like Staples; otherwise get a big set (even at Hobby Lobby - with coupon!) and break it apart for individual gifts.
