Schacht has developed a card that, at 3-1/2″ inches square, is comfortable in the hand without being bulky. Colored bands and stripes are printed along each edge to help you keep track of the card’s position. Made of sturdy yet flexible 24-point card stock, these cards will serve you well over many, many warps.
The cards come in packages of 25—more than enough for a range of projects. All you need to add is yarn and a belt shuttle.
