Hereof, what is the best size needle for tattoo outline?
#12 gauges are highly popular across all needle groupings and tattoo styles. Anyone referring to #12 or 0.35mm needles may also call them Standards. Common in lining and traditional work as they have a faster ink flow. Great for bold lines and colour packing/shading large areas.
Herein, can u use a sewing needle for a stick and poke?
With a careful use of dental floss and proper needle sharpening, you can get away with tattooing using sewing needles. However, these tools aren’t optimal for stick and poke tattoos since they don’t retain ink as well as tattoo needles and aren’t as sharp.
