what to get...

i have been wanting a tattoo in memory of my grandparents, expecially my grandpa. he died 5 years ago from brain cancer. he really meant a lot to me, he was like a father to me. and then about 3 years ago, my grandma died, she had lukemia, however you spell it. i want a tattoo in memory of them, but im not quite sure what to get. i mean i have one in mind, but im wanting to get other peoples ideas, because im not too very creative. to start off, i want something small enough to fit on the underside of my arm, somewhere around my elbow down to my wrist, thats the area i want it at. and a little about them, my grandpa was a preacher, he would go around to nursing homes and do singing and preaching. my grandma would always go with him, she was a very religious person also. she would never cut her hair because she said that god gave it to her and her hair would stop growing when he wants it to. it was long. anyways, they were religious people. they both loved hummingbirds, and my grandpas favorite flower was a pansy. and again, they both had cancer when they died. anyways, any ideas would be great. i dont want anything plain, like the normal cross, rip, in memory of... i do want it to be something that could be a remembrance for them, but that looks good. please?
