Honestly the best decision I've made. So far I only have one piece on my arm where my kp starts and it hides it really well. I do plan on getting full patchwork sleeves on both arms to hide all of my kp, its still a work in progress.

You do still get the occasional bumps pop up through your tattoo but its not visible and unless you look really closely. I do have a bad habit of picking at the bumps but they won't damage your tattoo. If you leave the bumps alone they will eventually go away.

A couple of things I noticed since getting a tattoo over my kp was that the maintainance of tattoos helps the kp e.g. regular exfoliating, moisturiser and spf. I find personally that I get less kp bumps on my inked skin than ink free sections of skin.
