After your consultation, your artist will sketch a design based on your ideas. You'll typically see the design on the day of your appointment. This is standard practice in most professional studios, as artists use that time to refine work right up until it's ready. If you need significant revisions, that may require rescheduling to allow the artist adequate time to redraw.
Trust the process. Your artist has the training and experience to translate your vision into something that works beautifully as a tattoo on skin.
