UNIVERSAL YARN Sandcastle is a self-striping yarn designed for lightweight garments and accessories with subtle texture and sheen. Each ball is 50 g with 115 yd (105 m) of a 46% cotton, 43% linen, 11% silk blend in the Reef colourway for warm-weather tops, shawls, and wraps. Hand wash and dry flat, and for larger projects alternate balls every few rows to blend natural dye-lot variation and keep the striping consistent.
