Ironstone Fun is a great thick-thin yarn! It is multicolored, so you not only get the varying texture, you get varying color too. Ironstone Fun would be great for quick knit gifts, like scarves and other accessories. It would also be fantastic for warm sweaters.
I ordered 3 colors of this yarn. The 112112 is the most beautiful yarn I have ever seen so I ordered more of it. Texture varies from very thin to chunky fat yarn, and it does fuzz up a little. I knit a scarf with 13 needles -of the black, white and gray. Simple seems to work best since texture provides the interest. With the 112112, I am making a vibrant shawl; it is lovely enough just to look at the yarn.
I'm a new knitter, and found this yarn pretty easy to work with. Despite the varying texture, it knitted smoothly, with a slight tendency to twist. I had to ball the yarn before starting my project, though—I learned that the hard way. The variations in texture and color make for a lively result. I liked it so much I'm getting more!
