Here is a link to a picture. It shows three women in tights. I can make the tights on illustrator, I just can't make the brownish translucent streak in the middle of each leg. The streaks are triangle shaped so I can't use a gradient, when I use a gradient mesh, the colors are too "blocky". I somehow need a gradient, not linear or radial, but that would keep with the shape of the leg. Thanks for reading and any advice.
