Fishnet stocking brushes to do a bit more than just using a texture layer for drawing fishnet.
These fishnet brushes can easily add fishnet to your drawings that get narrower on the edges to simulate wrapping around the legs.
They can be used as-is, or you can use vector layers with the Control Point tool to get a more accurate texture. If you adjust the number of nodes and align them within the legs, you can adjust the width using the Control Point tool so they conform to the legs.
