Just had my usual flop trying to put color into whole guinea skins... Used Rit and the bath looks orange, while the feathers look to be a weak yellow-olive instead of the desired bright orange...

Used salt for mordant, but the color did not take, so I have to believe vinegar would not have been any better.

My last success was with Tulip brand fabric dye and it did a fantastic job with purple. Enough so I thought I had things figured out. Right now I am back to square one because Tulip was not available in the desired colors...

I washed the skins in hot water and dishsoap, followed by a 15-minute soak in TSP, another wash in soapy water, and a rinse before putting them in the very hot dye bath. Maybe I should see if I can find red and yellow Tulip...

Any suggestions would be appreciated...
