Instead of utilizing a clamp and expanding out like an umbrella, this table swift screws together in the middle and uses the round-peg in the round-hole method to stretch the skein out.
Swifts range by size, type, and material; prices range accordingly. Ebay is a good source of cheap plastic umbrella swifts, premium woods and higher quality start around $60. I picked mine up at The KnitStore on Etsy.com for $34 with shipping. A lot of indie dyers sell their yarn in the skein; it's worth the investment to easily transform these pieces or art into usable balls to transform into your own pieces or art.
