Here is a silk scarf clamped and dyed Itajime style. Usually a piece of silk is folded and clamped between two pieces of wood. Then immersed in dye. I didn't have any wood handy. I used two ceramic tiles and a few lightweight clamps that I use for hanging heavier items on the clothesline. Also I used heat set paint instead of dye. I can barely wait for the sun to do its job so I can see the result.
