This design started as a test of various linear dither patterns to cope with the lack of usable gradient fills on Spoonflower. However, they could also be usable as economic indicator arrows or temperature change ones or even port and starboard - with a colour change (and in the other orientation). Other colours, sizes and orientations are available on request and you can even ask for a combination of several designs together.
