Just generally anything.
&& DIY/self-made Vs. Professionally done.
&& Your own stories/pics.
&& For or against.
&& And tips that you want to share.
&& Websites that have ideas for tattoo designs.
I know personally, I was thinking about having my first tattoo be DIY, since I was inspired by this new self-made heart tattoos. I'm not planning on doing a heart, but I still think the idea sounds awesome.
(PS I'm not sure if I did this correctly. Comment and let me know if I screwed up.) :D
