These are my basic dying tools along with Mason jars and the plastic beakers. We have put this package together to make it simpler for you to dye too! I use the syringes for measuring liquid dyes, for doing easy controlled spot dyes and stripes. The little cups are for measuring dry dye. The chop sticks are for stirring liquid dyes and poking and moving wool in the dye pot. The little baggie is a sample of the citric acid I used for setting colors. I use a Tbl to a yard of wool. You will need two AAA batteries for the scales.
