If you are looking for patterns for wonderful primitive art, lovely vintage graphics, or tutorials that make you go "Oh!", then go visit Our Pioneer Homestead. Pamela has a tutorial on how to use Walnut Ink Crystals, having aged some blue fabric to a wonderful time-worn hue. I'm eager to see what she does with this fabric.
I highly recommend this artist's blog--for all the reasons listed above, and because she has great decorating taste. :~) You'll be glad you went.
