this past weekend, i did this to some unsuspecting white yarn. the tutorial came from KnitPicks but as we don't have a microwave, i tweaked it. instead of 'zapping it' for two minutes, i turned the burner on under the pot until the liquid began to steam and quickly turned it off and set the pot on a trivet.
after the first round of this i pulled about 1/3 of the yarn out over the side of the pot and quickly learned that i should put a bowl under it lest capillary action make a pink swimming pool of my stovetop. after the second round of heating i pulled another 1/3 out and after the third round of heating, i left the last 1/3 in the pot and went for a (very blustery) walk.
stay tuned in the coming week for what it will become!
