The best bit is that the lowdown comes from YOU. Round here, you are the influencer. You shape the board and make it great. We want you to get involved by writing posts and comments to inspire us, teach us, challenge us or simply make us laugh. The power is in your hands, literally.
A successful cover up will depend on what you have in mind for the cover up design. Black is usually the most difficult to cover because it tends to bleed through. If you find an artist who has a fair amount of experience with doing cover ups they should be able to advise you better than random people on the internet who don't know much about actually tattooing (I've been a tattoo artist for 11 years so know what I'm doing)
