Dharma Fiber Reactive Procion Dyes

Pro's: Best dye for cotton, rayons, linens, hemp and other plant based fibers. Best dye for Tie-Dye and Batik. Vibrant wash fast permanent colors. Easy to use. Does not need hot water. Economical!
Con's: Colors are still vibrant, but shift on silks and wools. Need to use with the proper chemicals. Do not work on synthetics.

iDye for Natural and Poly Fabrics

Pros: Quick, easy, economical for small dye jobs, don’t have to buy extra chemicals, don’t have to handle powders, behaves like Deka L, additional 8 colors for Polyester and nylon! Results are even and not streaky.
Cons: Needs hot water, less brilliant and long lasting, may fade more than "professional" dyes, less color selection.

Industrial Dyes

Pros: Fast, easy, inexpensive way to dye large quantities of cotton, linen, rayon clothing, towels, rags, etc.

Natural Dyes (from plants and insects)

Pros: Historically fascinating to use dyes that have been in use for 100s to 1000s of years!
Cons: Fabrics or fibers have to be treated in a mordant before dyeing. Some of the metallic salts used to "mordant" (prepare for dyeing) the fabrics before dyeing are fairly toxic. We don't carry the worst ones.

Inkodye

Pros: When exposed to heat or sunlight reveals bright, beautiful colors on cotton, rayon, linen and silk; Very permanent!
Cons: Cannot see what colors they are until developed by heat/sunlight

Tie-Dye Cords

Pro's: Simple for children, no mixing of dyes and chemicals
Con's: Needs to be simmered on a stove. Colors not as vibrant as traditional Tie-Dye - much more white areas.
