General info: acrylic; slightly hairy (not anti-pilling); matte semi-gloss; loose twist; 4 main branches with many strands. Season: autumn-winter. Positives: this yellow colour is beautiful (light pastel yellow, baby yellow (colour 79203)); soft, elastic. Certificates/certifications. Iso; Iso; Washable; Colour fast; Size fast. 70% acrylic and 30% Amicor - the latter makes the yarn antibacterial, antifungal, hypoallergenic and odour-retardant. Negatives: few colour choices; recommended needle 4, crochet hook 5 - I think this is a mistake (I crocheted with 4 and 3.5, but could do with 3).
