Red Lanaset Dye
I bought a batch of Lanaset dye from Pro Chemical this week and here is the result of the red. It came out nice, I used about 1/2 tsp dye, a tsp salt, and water. I got very little blotching or spotting. I did dissolve the dye in some boiling water per the directions. After getting it to a boil I added a cup of vinegar, but I had way too much dye, so I had to add quite a bit of vinegar. I am excited about these dyes, even though they were pricey.
If you look at the picture, you can see a coral color sticking out there, that was the first pair I did with some food color I had, they were way off. I will overdye those in navy I guess.
