A chevron pattern, this is a 10 stitch repeat pattern, so you will need to either add 4 extra stitches to the basic pattern, or subtract 6. I add the 4. This bag is made of an 8 ply poly cotton blend string and then dyed with standard craft store "tie dye" dyes. I stretched the bag over a plastic bucket and selectively squirted the colors where I wanted them, yes, there will always be runoff and dye wandering where you didn't intend. I like that though.
