Tattoo ideas for a tattoo of initials incorporated in it.?

I am wanting a tattoo but can't think of a design. I am wanting something that can be for me but would also work on my husband or with a little tweaking could work on him too. I am wanting the first letter of our last name (H) and the first letter of mine (K), my husband's (M), and my son's (K) incorporated into some sort of design so it's not just letters. Also, I am not wanting something huge. Thanks!
