These easy-to-use tie-dye kits feature Procion MX fibre reactive dye, a concentrated dye that produces an exceptionally brilliant colour on any non-synthetic fabric. Each complete kit includes supplies to dye up to 15 adult T-shirts: instructions, dyes in magenta, turquoise and yellow, soda ash dye fixer, rubber gloves, rubber bands and an extra bottle for mixing pastels or secondary colours. The dye is in powder form in large plastic squeeze bottles. Simply add warm water to dissolve the dye and it's ready for use or for mixing new colours. The instructions describe and illustrate all the steps, including four tying techniques that produce different explosive patterns. For ages 12 and up.
