General info: acrylic; slightly hairy (not anti-pilling); medium twist; 3 main strands; thickness: light = DK = fine-medium = 3. Slightly flexible. Positives: colour and size fast (99%); does not require blocking; not attacked by moths; mimics natural materials but is more wallet-friendly. RUGALMAS - it can counteract the relatively stiff surface of crochet. This yarn is perfect for medium to large projects. It is easy to knit and care for (machine washable: gentle cycle, max 40 degrees). It has a beautiful colour (deep, classic medium blue with a slight steely tinge; effect: a stable, reliable colour that is not garish but not faded; elegant rather than playful; mood: a calm, slightly cool shade that goes well with more masculine or neutral-style pieces. Negatives: not soft, but brittle (although the ball itself has a distinctly soft feel). This yarn is not suitable for hats or scarves. Wrong needle suggestion on the grommet: a 4 or 4.5 knitting/ crochet needle is suggested - I think a 3 needle would work just fine.
