i did it, i dyed and discombobulated my scarf and it looks great! I'll show you each step so that you can use shibori too!
first: knit the scarf
i used cascade ecological wool in it's lightest color. it's untreated with chemicals which guarantees a good felt and it will take up dye easily. plus, they give you 478 yards which is a steal for 15 bucks.
then, place the scarf in warm water until all the air bubbles are out, and slowly add heat and dye (i used four packs of black cherry kool-aid.)
to achieve the gradation that i wanted, i slowly lifted the middle of the scarf out of the dye and continued to add dye to the rest of the scarf in the pot.
i added more and more dye while pulling the scarf out until i reached the end.
i rinsed it in warm water, then layed it on a table to figure out the bead placement.
i pressed the beads into the wrong side of the scarf so that the bubbles would appear on the right side and stretched the fabric tightly across the beads. i wrapped them with rubber bands and then i smelled very bad, like a wet sheep that swam in black cherry kool-aide.
next i threw that sucker in the washing machine with some detergent. i made sure that water was hot hot hot! and out popped a fabulously felted scarf.
i took off the rubber bands, popped the beads out and presto! cool scarf!
