This method gives me the best results and I have dyed Doc Mego's stuff, CTVT's stuff, and even the PMAJ clothes with pretty good success..... I got it from "Custom Uniforms by Mary" -- can't take credit for the technique.
Step 1: Get the water boiling first. Add some salt if you're doing cotton or polyester fabrics (I added about 1/2 cup). This will help the dye soak into the fabric. When the water is boiling add the Scarlet dye and blend well. Use a pot that you will never cook with again.
Step 2: While the dye is returning to a boil wet all the stuff you want to dye. WEAR RUBBER GLOVES--SQUEEZE out the excess water in your fabric--you don't want it sopping wet, just damp. Add this to the boiling dye mixture.
Step 3: Boil the fabric for about 5 minutes. If you have a lot of folded pieces be sure to mix it up good and stir constantly. Poke and turn the fabric over. I use a wooden spoon for this. Keep all the pieces of fabric submersed in the boiling mixture at all times.
After boiling for 5 minutes lower heat and simmer for another 5 minutes then remove the pot from the burner and let it all cool for another 30 minutes. Now it's time to rinse your fabric items. Keep in mind it will look lighter after it dries. Rinse WELL!
Step 4: After a GOOD RINSE, let the fabric dry completly. If you're impatient like me, you can use a blow dryer.
Don't be sorry. How would you know? You've been watching MTV all your life.
