From Piecework Jan/Feb 2011:
When asked to design these cuffs I immediately thought of some lovely hand-dyed S-plied wool/silk Prism yarn from Lambspun of Colorado that I had previously used for two-end knitting. Although Z-ply yarn is easier to work with for two-end knitting, an S-ply can work well if knitted with needles somewhat larger than those typically used for an S-ply yarn. The patterning in these cuffs has just enough change of pace to keep it interesting. It also controls the silk’s slipperiness and drape so that the cuffs will fit nicely without sagging.
