Softer than a kitten, fluffier than a cloud, Wonderfluff is a technological marvel! Silky baby alpaca and fleecy merino fibers are blown into and caught in a lightweight tube of nylon mesh. The result is a yarn that's beautifully bulky yet lightweight and warm, with surprising resiliency. Wonderfluff works with a wide range of needle sizes and with 142 yards per 50g, the generous yardage allows for large, luxurious projects that won't break the bank.

I'm making the Professor Meow sweater, and have not had any shedding at all. No knots or thin spots in four balls used so far. I do fluff the balls up before using by pulling out a bunch of the middle to make air space, and try to work with a light hand, which seems to help achieve smooth stockinette across rows. It's 70% Alpaca and only 7% Merino, so it's not going to be elastic. I have also dyed the Wonderfluff 'Bare', and did lose fiber during long soaking in the dye bath, so the end result was a thinner yarn, but still fluffy and very usable when dried, without thin spots developing.

I started knitting the Suzy cardigan (Knitscene Fall 2018) last week, and even though I am just past the waist it is already my favorite sweater. So soft and lightweight, and the braid across the back stands out beautifully. I think because of the fuzziness this yarn works better with big cables or stockinette, rather than with more detailed, finer texture. I tried making a swatch with a moss stitch and most of the detail got fuzzed out. The Atlantic Heather shade has so much interest to it that it seems to change color depending on the light. Sometimes more blue, sometimes a little teal, sometimes almost navy. I would definitely recommend trying this yarn.

I used this yarn on a large order of hats which was very specific in the colors they wanted so I stuck with it. This yarn is soft, nothing like the Reverie yarn, but still fluffy and soft enough. The shedding was unbelievable. It’s an interesting construction with the fibers blown into nylon tubing, but it means those loose fibers escape easily. When I blocked my finished items everything was shedded on, which leaves less merino wool on the actual finished work. It was very disappointing. I love the colors. I love the halo. The construction is horrible.

Lovely yarn, but I'd like to see some patterns for long-sleeved knits in this yarn. It seems silly to have yarn this warm, but only have patterns for sleeveless tops.

I used this yarn to knit a hat for a friend. The hat turned out nicely, but I'm unlikely to use this yarn again. It was very hard on my fingers, causing multiple splits in my fingertips, and I had to wear finger cots to be able to finish the project. I'm sensitive to superwash yarns (possibly the chemicals used to make them superwash), and this isn't a superwash, so I wonder if it may be the nylon mesh in this yarn that was so hard on my fingers. While this yarn may be wonderful for most, and I liked the fabric it produced, I have to give it an average rating due to its harshness to my hands.
