Jack & Sally consists of 2 x 100g variegated skeins - one in blue, green, pink, orange and yellow, and the other in black and white.
This base is a blend of 75% superwash Blue Faced Leicester/25% nylon. It is a sock/4ply/fingering weight yarn.
100g = approx. 425m/464 yards.
If using both skeins for the same project, it may be advisable to swatch the two different skeins to be sure that your gauge is the same with both - on occasion different dyes and dyeing techniques can affect yarn.
