The yarn topic made me remember a good yarn material source. My teenage son was into camo everything when he started hunting a few years ago. He wanted his grandma to knit him a scarf with the camo-colored variegated yarn he saw an WallyWorld. I was checking out the left over and realized it had 9 different colors from black, 3 shades of tan to brown and 5 shades of green (light olive to dark olive brown). Each color about 8 inches before fading into the next. I cut it by color, sorted it and bundled each color of about 25 pieces. Thinking if one can buy 9 colors of earth tones for a couple bucks, what else is out there? So now I check out the full size yarn skeins whenever possible and found a variegated chenille with many possible colors.
