Giving my clients what they want is very important to my work. Grandma was quite the avid crocheter, but the artwork I drew up using the center… Stitched(?) Crochet work had a rather unfortunate resemblance to a butthole. Tattoos are permanent and memorial tattoos are very personal - it’s more important to make them attractive and meaningful than factually correct. I would hate to have someone mention something like “hey that looks like a butthole!” thinking they were being funny and cause a client to feel embarrassed or upset about their work. It is hurtful to both their self image and their memories of the person they got the tattoo for.
