One year I got a really neat gift from a friend; in a mason jar, she had put all the ingredients to a cookie, with an instruction sheet on the side about adding water, etc. It was great because I was able to save it until I wanted more sweets (it was too close to Christmas to have even MORE cookies, etc.). I will see if I can find the recipe online for you.

I also think your spaghetti bags are a GREAT idea! I may use that in the future
