Twisted Pam asked what dyes i used on these rovings, so i'll do the best i can in describing them. Mostly, i use Lanaset dyes, and a few Pro WashFast. In the reds, pinks etc merino/tencel roving i layed the wet fiber out on plastic wrap, snaked back and forth in about a 2 1/2 foot length. starting with copper (L scarlet, brown and gold),
then L scarlet,
polar red,
scarlet with small amount of either polar red or L magenta,
L magenta with sml amt polar red,
then WF violet
*(L=lanaset and WF=Pro Washfast)
smoosh the dyes in to be sure they go all the way thru, add vinegar, wrap up the plastic wrap and steam (~45 min)

reds
same procedure... this time the dyes were:
olive (add tiniest amount of L brown to lime)
lime ( L yellow = small amt. L green)
L yellow and L gold mixed about 1/2 / 1/2
copper
L brown w/L gold
?L magenta +WF violet (not really sure what this is)
WF turquoise
magenta (same as above)
L yellow w/a few drops of brown
Lyellow + gold
I cant give you any exact formula as i dont keep records. i just add dyes to each other in a plastic cup or a jar and swirl it around ... when it looks right, i pour it on the fiber. let me know if you have any questions... maybe i can answer them :-]

turq, purple etc
