Here is all of the Avatar the Last Airbender patterns I have done (minus the Korra one posted earlier).I did have Appa, Katara, Sokka, Momo, Azula, and Iroh, but I'm not happy with the patterns and need to test them first.
Black- Do nothing.
Dark Grey- Carve pumpkin skin but leave pulp alone.
Light Grey- Carve pumpkin skin and about halfway through pulp.
White- Carve skin and pulp away so the light can shine through.
If there is a pose or character you want, I am taking requests and I do this for free. Just send me a link to the screenshot and I'll do my best.
I also have several patterns of various Danny Phantom characters done- Danny in phantom form, Sam, Tucker, Jazz, Maddie, Jack, Vlad human and ghost, Ember, and the wolf ghost.
