Cover up eith line needle

My wife had this tattoo that the father of her children did and it was really messy and messed up and disrespectful bc it had southern bit.. On her and it was a tattoo that she person chose to cover up. Now I've just been relieved from prison and i did a lot of tattoo work incarserated. So when you tattoo in prison you learn to shade with a line needle. So more than anything this tattoo ment a lot for me to do because I love my wife and she didn't believe that I could tattoo fully with just a line needle and the size i used was rl1 and 3. But i still new to learning about what needles are what so i would really like to know what you all think and if possible give me feed back on what you think also for anyone who has never used a rotary motor you should give it a try its light weight and really there is not much vibration to it and if you go to deal because your a heavy handed tattoo artist the motor will let you know by jumping on you its very well worth every penny
