Changing your mind about a tattoo design before your appointment isn't a tattoo taboo. The key is all about timing and communication. Talk to your artist early, be upfront about what you want, and understand that some changes might come with extra costs or a schedule shift. Remember, a good tattoo artist wants you to be happy with your ink, so working together is always the best approach. Don't be afraid to speak up if you need a tweak, just be respectful of their time and artistry. With clear communication and planning, you can ensure you get the tattoo you'll love for life.
