my husband is a writer and i am an artist. he writes me poems and i draw things for him, those are always the most treasured gifts. niether of us are shoppers anyway. store-bought gifts never impress the way something that takes time and love to make does! You don't have to be an artist. you might be a good cook or a story teller or a gifted seamstress. Even if you don't consider yourself artistic at all, a simple list of all the things that you find immeasurably wonderful about him would boost his ego and show him how much you think of him.
For Christmas this year, my Father In-Law actually sewed me re-usable grocery bags with the words "super mom" embriodered on them. He can't sew! But he did it for me and it meant the world. (Did I mention that he is extrememly wealthy and could have bought me whatever he liked?)
All of those kinds of things would probably feel better than a store-bought anything when money is tight. Or when it's not. It's the love.
Happy V-Day and congrats on your beautiful family!
