Im in the middle of getting a koi on my am. taken 5 hours so far, an hour for the outline. 2 hours for the blues and 2 hours for the fish and flowers. took so long as he used 9 shades of blues and 6 shades of orange and pretty much all the coluring was free hand (not looking at the picture)

Still got 2 hours left, as he wants to put greens in with the blues and carry on up to my elbow.
after care is important but they should go through that with you, I found pile cream ontment to be good as kept it moist and didnt dry scab, just peeled off whn was healed enough
