Swedish Wooden Swifts
Umbrella Swifts are made from birch, in two sizes, the regular size which holds skeins up to 72" around, and the large swift which holds skeins up to 100" around. They are constructed and finished to get the most appropriate surface for the yarn.
These are the original Swedish made swifts and not an imitation. Look for Sweden on the logo.
You can clamp these swifts to stand vertically, as shown. Or you can mount them horizontally which can make for easier un-winding. Use the swift in conjunction with the ball winder.
This is the swift you see everywhere, for good reason. It clamps positively and stays put, even if mounted sideways on the loom's castle. It is sturdy, supports a heavy skein, and should last a long time. If you are going to have just one swift, this is the one to buy.
