I am making an afghan with RHWL and I love it.
I have always been torn between using the original RH yarn and other brands like Simply Soft. I like the stiffness of the original RH. It seems to hold its shape better, especially when making squares, but it is not soft at all. And when I made my last project using RH, the lighter colored yarn was thicker than the darker colors, so the size of my squares wasn't consistent. I also came across several knots in the skein. On the other hand, Simply Soft is so much softer, but so limp and separates easily. So recently I decided to try the RHWL.
When I compared the RH with the RHWL at the store, the RHWL was thicker and softer, but not limp like SS. I am using a light color and a dark color for my afghan, and the thickness is the same. I love the way it feels and the squares are working up nicely. I have not finished the afghan, so I haven't laundered it yet.
It costs a little more, but it is definitely worth it. Our local Walmart doesn't have a very good selection though, so I guess I will make a trip to Joanns.
