Stanwood Needlecraft carries two different styles of yarn swifts - umbrella style and Amish style. Both are made of high density solid wood that will last for decades. Umbrella style swifts have two sizes - medium (6 ft) and large (8.5 ft). The wooden surface of our swifts is smoothed by super fine sanding paper and will never snag your yarn. All of our yarn swifts are covered by an unconditional ONE year warranty.
