Anne,
If my energy came from a bottle I'd share. My mind won't rest when it has thoughts running through it. I'm probably low on melatonin or some other supplement!! For now, I'll just take a nap if I need one.
Dorothy,
DOS means depth of shade. Sometimes you will see WOG, which means weight of goods. Basically it's 'how strong' you are making your dye stock. I weigh mine, as there is so much difference if you dry measure the powders. When you get dye powder the company will put it in the smallest, yet adequate, size of container. Golden Yellow is very 'airy' so it actually needs a larger one. This picture shows 2 containers, each holds 2oz of its named dye.
So, if you are measuring the dry powder by teaspoon or tablespoon, you most likely are not getting all of your colors to the same depth of shade. This is not a big deal, but anything over the 4% tends to waste dye and the washouts take a lot longer. I started out this way, but since taking Candy Glendenning's classes I have gotten more structured with my dyeing. I still find that I like doing serendipitous dyeing too. That would be methods like ice dyeing, thickened dye painting, marbling, etc etc. When doing these it's just too unpredictable to try to figure out exact amounts of dye for size of fabric.
Now for how this actually work so:
5 grams of dye powder in 240 ml of hot water, this used on 1yard of P&B Dyer's Muslin, and left to batch for 24 hours in a very warm environment resulted in these
I hope this is helping you and not confusing. Many dyers don't measure the powder by weight, in fact Candy is the only one, that I remember, that did. Don't stress about it, but if your rinsing out is taking a lot of time, try using less dye powder in your solution, keep things very warm, and try to batch for 24-48 hours.
Have a great day,
Luann
