Wasn't having a "GO" at you Tabbycat, just merely passing comment based on previous comments, so I apologise if you thought that.
Regards your wanting to tattoo your eyebrows, have you tried having eyebrows tinted? Many have tried to get me to do it, as I'm very fair, but I have resisted. However, I've seen folk who have had it done & it looks good. My son's girlfriend got a procedure done, not sure what it is, but it's not tattooing. She used to pull her eyebrows out, until she had virtually nothing left. She gets it redone every few weeks or so, though I believe tattooing lasts for much longer. Her eyes look much more defined now.
