I'd advise to start with the bottom part of your arm and then finish the top with the last 100 lost, I'm at 180 and personally my upper arms aren't there just yet but from 247-186 I've lost 6 inches from my upper arms, my lower arms have tattoos on them, but I know sleeves have to be done in sections anyways, good luck and share when you do it!
