With my outline he used a 7 needle but he said the needles are so small I wouldn't be able to see them. The girl I work with got her side done and said it was like murder for the color.
I guess I'll never know until I get it done. There is actually another artist stoping in to help and I might see about getting one done by him in the next week or two, but this one will be on my leg. Not sure what it will be though haha.
