Ashford Hand Cards. The "standard" style (not shown) is the typical curved solid wood card with a turned handle attached with glue and wood. Choose the coarser wool cloth (72 psi - psi means "pins per square inch") or the finer cloth (for fine wools, cotton, angora, etc.) version with 108 psi. Also available are the "student" cards (shown). They are a curved plywood one piece card with 72 psi carding cloth. They are strong and are also a good price. For children and people with smaller hands, choose the "mini" hand cards. Made from one piece of curved plywood (similar but smaller than those pictured) and with 72 psi, they are strong and lightweight. All of the above are sold by the pair. The flick carder is a small, one piece card with a turned handle and 72 psi cloth. Hand Carders are priced and sold in pairs, Flick carders are sold individually.
