3 x 25g balls + 21g of 4th ball. Isager Soft Fine is designed as a finer version of the extremely popular Eco Soft brushed yarn by Isager (which has been renamed Soft now that it comes in dyed as well as undyed shades). It is constructed in a similar way, but with a silk core rather than a cotton tube, and contains an incredibly soft mix of alpaca and yak fibres to give a wonderfully luxurious effect, whether held on its own, held double, or combined with other yarns. This is a good alternative for those who are sensitive to mohair.
