I dyed some cotton punis the other day:
I deliberately didn't try to get a solid color here. I soaked the punis first, made a dye solution and just poured it on kinda randomly.
I was pleased with how they came out. One interesting thing: I squeezed the water out of the punis when I was done dyeing, and they were pretty tightly compressed. But they fluffled back up as they dried! Cool.
Here's a closeup, though the color's more accurate in the first picture:
And I'd just like to extend my condolences to the family of Ruth, the Twisted Spinster. I'd just recently gotten to know her online, and was enjoying reading her blog about her cotton, and her vacation. It was a huge shock to find that she died suddenly the other night.
Peace, Ruth. I wish I'd known you better.
