Here is another way of using dye cubes. Left over dye concentrate was poured into ice cube containers and placed in the freezer. Two fq's of fabric were soda soaked.
One piece of fabric was placed flat in a container and dye cubes were placed at random on the fabric. There is a piece of cardboard in the container covered with plastic. This gives enough raise so that the fabric will not be in the melting dye.
This is not my best picture, but you get the idea :-). The second piece of fabric was placed over it.
This was left batching till the next day. After rinsing, washing and ironing the fabric looks like this:
I had not marked which fabric was at the bottom and which at the top. My guess is that the top picture shows the fabric which was on top and that the bottom one was as the bottom. The colors blend a bit more on that one.
Having seen these results, I make certain that whenever I have some dye concentrate as a left over, that I freeze it. With frozen dye it is difficult to see which color it is. If you want to keep track of that, I suggest that after freezing, you put the dye cubes in small ziplock baggies on which you can write which color is in it..
