I have been looking for a easy method to paint marble effect as it is pretty cool material in terrain.
Additionally, I have been stacking up on vitamin tubes until I would find such an method. The day has now come, and I think I found good, fast method to produce marble in tabletop quality.
On the plus side, you get shitloads of vitamins while collecting these.
I also constructed a stick that holds the container while I paint it further, and allows me to rotate it on the spot.
I did not vary paper distance as I wanted the edge of the pattern to be clear and hard.
Then I used Vallejo's sepia shade heavily dilluted to wash them and tie the effect together, it took the edge and harshness away from the pattern.
Lastly, gloss spray to make it more marble like.
