I worked with the cascade yarn for two projects. The first one I did was a blanket and a beanie for a baby for which I used the 327 and I worked pretty good with the yarn and everything. For the second one however, I used the color 221 for a baby blanket, unfortunately I miscalculated the amount of wool needed and I had to order more which resulted in having a two color blanket as it was from another lot number.
Also, even if the recommendations tells that you can put it in a dryer with low temperature I won’t recommend, it made little wool balls in my blanket
