These are hats # 4 & 5 - Adult-sized in my typical Brioche hat pattern. I needed some samples for the class I'm teaching at the end of the month, and these really are super-quick.
I was struggling to find super-bulky yarn... so the hat on the left is made with a couple of handfuls of left-over bits (blues and greys) of worsted, held triple. If I ran out with one ball, I just grabbed another. Super-bulky is faster and easier than dealing with three strands of yarn, but, it sure does feel good to use up some of the odds and ends basket yarn instead of always adding to it.
The hat on the left was made with Lion Brand's Jiffy-Thick & Quick - a nice, soft, super-bulky yarn. The cost is right for charity hats. The content is 100% acrylic (which is right for my allergies). The weight is nice, the yarn is great for showing stitch definition. BUT. It only comes in highly variegated colors. No solids. And really? Only about a half-dozen variegated color options at that.
Review? Highly sold on the yarn. Not high on the color options and this is not going to be a yarn I purchase much of in the future as a result.
My favorite for these WAS Lion Brand's Wool-ease Thick & Quick . But now that my allergies have worsened, I break out in hives if I work with that yarn. But, a shopping trip last night got me on the trail for another alternative. I'll do a review after I've used it, which might not be until March... but I'll let you know.
