Silk Cloud is a scrumptious mohair and silk blend from Shibui. Similar to Rowan Kidsilk Haze but with a higher proportion of silk (60 mohair/40 silk) and more yardage (330 yds), Silk Cloud creates a gossimer light "cloud" of fabric in lace designs and adds a soft halo when added to other fibres.
Here's Alex's swatch for a top down pullover, using Shibui Silk Cloud and Elsbeth Lavold Silky Wool. The resulting fabric, a luscious silky mix, must be felt to be appreciated. Her swatch, knit with 5, 5.5 and 6mm needles ranges from 16 to 14 stitches per inch.
