I make them cards. This is I think the cheapest and at the same time one of the most specialized gift I could give to my mom. Not that it's very personalized and unique, it also comes originally from the heart and from my mind. Also to spruce it up a little I make a bouquet of flowers out of our garden or basket of fruits. I really don't spend anything except for some decorations that I use to decorate the basket to where I compile them.
