I bought both yarn at Diteksas in Vilnius. The grey one is mohair-polyamide blend with the yardage of standard thin mohair (25 g/220-250 m), the black one is wool-polyamide blend, in the range of 100 g/1500 m or even lighter. Double moss stitch with this yarn gives an impression of uneven fabric like bouclé. This sweater is “my” sweater: vey simple shape and pattern and grey.
