First pattern trials: Pueblo

I am currently researching patterns found on pottery made by the Pueblo people, especially Acoma Pueblo pots. Thus I've been copying images of pots I like and am drawing parts of these patterns that particularly appeal to me. I've noticed that there are endless variations on quite similar basic patterns often using a very limited range of colours.

Today I've tried to loosely transfer some of these patterns onto a cup I've thrown. I am trying out a specialist ceramic design fineliner for the black lines. This is more difficult than I thought it would be. Not only can the fine nozzle clog up but because one has to press the bottle to squeeze the black underglaze ink out it is rather strenuous and my hand started aching. This causes the lines to be even more wavy. I think, the design line works well for organic drawings but maybe not for clean geometric ones.
