i think y've already received so many great ideas. I hope y'all find one that works. I just wanted to point out how lucky you are to have a mom that doesn't mind not getting a store bought gift. My mother in law was told by her oldest daughter that they'd had a tough year financially and that her husband was really insisting that christmas be about the kdis in the family and that adult gifts would have to be forgone in favor of saving money. I personally think that's fine since in my family we always made christmas about the kdis and the grown up rarely got much from kids or extended family. Well my mil got all upset at my sister in law about that b/c she wasn't going to get a gift. when my sil started telling me the story i thought perhaps mil was more upset that the family as a whole would be exchanging less gifts---like it wouldn't be as fun for everyone or soemthign? well, since she said "will you "at least" have the kids draw me a picture?" i figure that i was wrong and she really was upset about being left out! i couldn't believe it. I certainly hope if my daughter ever comes to me saying they are having financial trouble, her husband's job is commission only, and they needed to cut back--well, i hope i'd say, honey, how can i help and don't worry about me. For one thing, my mil has more stuff than a person could want and more than she can store, that's for sure.
so, anyway, give your mom a hug, make her some fun handcrafted gifts and have your kids put lots of love into them....she'll love them and everyone will be happy.
I didn't read every one of your replies, and i know you got some good suggestions, but i'll stick a list of my own thoughts below. oh, and remember, consumable items are always nice b/c you don't have to store them, display them forever, etc. though sometimes kid crafts are too cute to every part with.
list:
handmade cookies, breads, etc
handmade bath products. I have a small business and make and sell bath and body products including glycerin soaps so i don't really recommend buying the craft store glycerin soap base...its not very good and really expensive. however, you can make great bath salts etc just from items you find at the grocery store. Pick up some dead sea or sea salts, epsom salts, and a little bottle of essential oils (usually from a health food store- peppermint is easy to find and also less expensive than some others) and mix it all together with a few drops of the fragrance. easy way to do it for kids- just get a gallon size zip lock bag. put in your salts, a few drops of essential oil, a few drops of food coloring (ok for a project like this but not what I use---the gel kind works best) and then seal the bag with as little air as possible (or the bag could pop open) and have them squish and shake it til it's all mixed. Put in a pretty jar, use a clean sea shell for a scoop, and put a ribbon on.....very pretty, cheap and easy!
make cinnamon/applesauce cookie ornament sets with the kids(look up recipe online- super easy- mix and cookie cut out/dry/bake)
handmade or computer created mini photo books. this can be as easy as colored paper, prints, stickers or just text with a ribbon binding. or go to a store like CVS and ahve them make one- though that's still "buying something".
A photo calender- instead of having photo shop do it, just print on your home computer/printer and add photos.
picture frame from scrapbooking paper and/or board. have the kids paint it or decorate somehow....decoupage is really really easy and you can do it with elmers glue!!!
reuse something in your house....redo it like paint and decoupage a chair, bench, frame, step stool...etc.
pick up some plant pots and have them paint with appropriate outdoor paint. these are really cute and don't cost much.
make christmas tree ornaments from anything- felt, fabric, paper...the ones the kids make at school or home are our most treasured. put their names on them, maybe a cut out for scohol or other photo, and the year of course.
good luck!
