Cover up advice?

I had a very small (1cm by 1cm ish) tat of a hexagram done in black yesterday. peoblem is, it's not what I wanted! I wanted a pentagram... Tattooists mistake... So I have been offered a cover up, but I'm unsure what to get? I wanted the penta in the first place that size because it was small, thin lines and looked delicate. now I'm gonna have to go bigger to cover the hex with something else. Bit I'd still like it to be pretty small and delicate. Any ideas? Also - since it was only done yesterday, is it worth just waiting for it to scab and trying to pick some of it out? Might make it easier to cover unless it scars?

I don't really see this as the tattooist's mistake, as you must have seen the pattern, and then allowed them to put this on you. Next time speak up, it's your body after all.
