These vellum strips are the newest thing in the world of quilling. They are called "color blends" because they start out one shade and the color changes as you go down the strip. These are very different than graduated or dark center strips because they actually have different colors along the strip instead of different shades of the same color and of course they are vellum which makes them translucent. They are 1/8" wide and 12" long and there are 100 strips in a pack. Eack pack includes the full spectrum of colors, purple/red/yellow strips, green/blue/purple strips, red/orange/green strips, blue/green/yellow strips, and yellow/pink/purple strips. Of course we still carry our solid color vellums as well.
