I knitted with 3 yarns that I had never knitted with before today… Here’s my humble opinion:
Berroco ‘Comfort’ Worsted Weight (50% Nylon/50% Acrylic) - Although it felt wonderful to the touch, the yarn split alot and came ‘untwisted’ (loose fibers)
Knit One Crochet Two ‘Wick’ (53% soy/47% Polypropylene)- AWESOME to the touch and to knit with. The stitch definition is terrific (great for a beginner) and it doesn’t split easily or lose shape (I FROG alot and some yarns will lose their shape if you FROG and re-knit)
Naturally Caron ‘Spa’ (75% Microdenier Acrylic/25% Bamboo) - Loved it’s sheen and silky feel. Really pretty and pretty good stitch definition. Did not split easily.
There’s my 2 cents.
