So I have some amazon gift card credit, so I was thinking of ordering tattoo needles instead of using sewing needles. What kind would be best? Shader or liner? I was just gonna get 5rl. I have no idea what the difference is.
Get a 3 liner with '00' needles, spiral ground if you can find them them, they are a lot better for handwork.
Ink wise, if you can't get tattoo ink then use either Rotring technical pen ink or Pelikan (if you can find it).
India ink often contains shellac and should be avoided.
