Dyeing some 8 value swatches for some students, and myself. I am working on a couple rug hooking projects using the fine shading technique. Hand-dyed swatches are useful for realistic shading in flowers, leaves, and fruits and vegetables, of course animals and people also. The range from dark to light helps define the object, especially useful for the high lights and darker shadows. Fine shading takes practice, lots of visual aides, and patience. There is a logical step by step way to fine shade for realism, and if you have the patience to follow the process it really works.
When my project is finished, and I am happy with it I will post the picture. Hoping by the end of the week to have it complete.
