Do yo have a picture of what this looked like? I've been trying to master this technique and I'd love to see how yours came out.
using a shirt as an example:
use somewhere that can have dye go down the drain, or into a large basin. soak shirt in soda ash, and wring out. NOT dry. say we use orange. lay the shirt on something raised off the base of where you are dyeing, and if any way at all, tip up just a bit.(so dye runs off the side of the shirt... not top or bottom.) i did mine outside over a big oil drain pan, on an enamel rack (the kind they sell at home stores for 2$)you can lay out the shirt flat if you have room, or gently fold it up so you can make horizontal lines.start at the bottom, and squirt on a strip (2 inches, 3 inches...) of straight orange dye. unscrew the top. add some water. add another line that overlaps the edge of the first line. unscrew, add water. repeat. repeat. you can do a ton of grades. i did about 5 grades. one in orange. one in fuschia. then i did one in orange down to clear starting on the bottom; and fuschia down to clear starting at the top. make sure the stronger dyes can't roll into the weaker dyes to the point where they take over. this is by far THE easiest dyeing i ever did. and its also a great use of leftovers from a project, you are only using the initial amount, and the rest is water. BTW, no alginate is easier, excess goes over the edge , instead of lingering and getting a chance to wander on the cloth TOO much. my 12 year old niece loved them, and they are on their list of acceptable "in" colors... (aka hombre dyeing)
