I've made many a gift for my boyfriend, some of which include a little chocolate box decorated like a romantic place setting for 2, a miniature guitar case painted with a portrait of myself with a little guitar pick made from drum cymbol inside, a few cakes decorated by moi, a hand-knit scarf, a wallet, and quite a few cards. Here's a picture of one of the cards I made him. It says ani ohevet otcha in the bottom corner, meaning "I love you" in Hebrew (he's Israeli). It's not perfect but I still like it.
It's done solely in ink and watercolors. <3
