Our 100% wool roving is blended shades of wool fibers giving you a fabulous result when needle felted. Each fleece color is dyed-in-the-wool to maximize brightness and color fastness. Then two, three, or sometimes four colors are blended together to create the beautiful heather mixes in the roving. The Wool used is the finest imported Merino Cross Wool from New Zealand with a short staple that is perfect for needle felting. Each knot weighs 1/2 ounce. Enjoy!
