Re: [BKARTS] Dark spots on fair leather, Hewit dyes general question

Hi Juliayn,
I would check directly with Siegel's. They are usually very helpful and
answer any questions I have very quickly. They have an 800 number.

Does anyone have any ideas about why fair leathers produce tiny dark spots
when wetted out, or how to avoid or minimize this? I am working with a fair
(undyed) vegetable- tanned goatskin from Siegel's of California, trying to
dye it a sunny yellow with Hewit dyes, but dark spots have appeared after
wetting out the leather. There is a photo here (you shouldn't need a flickr
account to see it, hopefully):


Thanks for any advice or input. I think I'll be moving to a darker color for now, which has prompted another question for me: some of my Hewit dyes, such as the mid blue, are not dissolving well. I used about a teaspoon of dye in a couple tablespoons of water, put it all in a small lidded jar, and have been shaking it quite vigorously, but there are many dark crystals which are not dissolving. Any ideas? I have looked around a bit in the list archives, but have not seen anything answering these questions.
