I save security style mailing envelopes that have interesting textures inside. This week I used an envelope to experiment with a background texture for the dirt ground surface in the Ecuador piece in progress. I use a sample quilt sandwich on which to 'play'... til I settle on a style that might work on the 'real' quilt.
I started the exercise including the occasional repeated hatch marks attached to a linear quilt line.... I ultimately decided not to directly include hatch marks but kept things moving a bit more. The result was somewhere between a directional meander and wood grain.
