Preparing Fiber Reactive Dye Solutions

• Mix dyes ahead of time to use time to assist with fully dissolving the dye
• 16 ounces bottle work well - right size, tight caps, fit in 6-pack, easy to shake 
• First, determine how much dry dye you need - Dharma Trading has a of amounts. They've created a calculator. Very Nice. 
• I use mass amounts to decide the amount of dye powder. 
• First, add the dry dye (using the small 'weighing boats'); 
• No urea (urea is a help to dissolving). I may not need it because of the characteristics of my local water supply or because of my willingness to prepare my dye several hours ahead of time (check with experts such as Paula Burch). 
• Add 12 ounces plain warm water. 
• Cap and shake. 
• Add salt, usually 1 tablespoon; shake again, and wait. 

Note on Measuring Dye: I use information provided by Dharma Trading to determine the amount of dye and go by weight -  measuring in grams using digital scales and weighing boat. (Term to use for googling: dye yield).
