I haven't tried the Lion Brand's "Cotton Ease" yarn, but I bought some of Bernat's "Denim Style"
the other day to use to make a summer hat. I knitted up a gauge swatch and the yarn seems very nice to work with--it feels very soft and cottony, but has some "bounce" in it (from the acrylic I guess?). I'll have to see how it works up, but all in all, I was pretty pleased from my gauge swatch with the results. The yarn seemed to me to be almost better
being a cotton blend because it has more give to it than 100% cotton yarn. Denim Style has less cotton than the Cotton Ease's (70% acrylic, 30% cotton for Denim Style and 50% acrylic, 50% cotton for Cotton Ease), but the gauge is almost exact. I'm curious to see how the two compare. Cotton Ease has some pretty colors, too!
