This is DK (double knit) weight base. This base has 75% Superwash Merino Wool and 25% Nylon. 4/9NM, 225m. per 100gm.or 250yd. per 3.5oz.
While it may be machine-washed, I recommend that products be hand washed and lain flat to dry. Also wash dark colours separately or wash a swatch before using dark and light colours together.
As with all hand dyed yarns, we would recommend that you use two skeins at a time, alternating from each one every couple of rows/rounds (unless it's a one-skein project).
