Bright Lights is a variegated cotton yarn dyed in a bright rainbow of colors. 100% Pima Cotton DK / Light Worsted Weight 100 grams / 200 yards Care: Machine wash, tumble dry low. Please note: you will need to wind this yarn into a ball before use. It cannot be used straight from the skein like commercial yarns. All of my yarns are hand dyed and every batch is one-of-a-kind. Please make sure you purchase enough skeins to finish your project, as future listings of the same colorway will inevitably look a bit different. As with any hand dyed yarn, please expect minor imperfections and some variation from skein to skein (even within the same batch), as each skein is individually hand painted. I use professional fiber reactive dyes on all of my cotton yarns. These dyes actually bond to the fibers of the yarn, making the final product extremely colorfast and fade-resistant. After dying, all cotton yarns are washed with special detergent and then rinsed several times. I do my best to wash all excess dye out of my yarns, but it's always possible for any yarn (hand dyed or mass produced) to unexpectedly bleed color later when washed, or "crock" (react with the user's skin causing staining during use). If you are planning to mix this yarn with other colors in a project, I strongly recommend doing a test swatch first.
