The yarns are 4-ply worsted weight acrylic. I'm not 100% sure of the brands because they were both mill-ends bags purchased from AC Moore. I do believe the grey is 'I Love This Yarn' though - it's got the same look and feel. I used a 'J' hook and the finished measurement is 24" square.
I've already started another blankie - it will be an 18-point round ripple. The yarn I'm using is one I bought from Michaels yesterday. It's called 'Craft smart' and the color is 'Tumbleweed'. This yarn is new to me - never seen it before. On the label it says "Distributed by Michaels Stores, Inc.", so I would guess that Michaels is the only place to get it. The feel of it is like Red Heart Super Saver - so I'm hoping that after I finish the blankie, a quick run through the dryer with a damp towel will soften it up. I'll keep my fingers crossed.
The price of this yarn is $2.49 - the variegated colors are 5 ounces, and the solid colors are 7 ounces.
This 18 point round ripple is based on Angelfire's round ripple - I added an extra increase round at the beginning and then changed a couple things. I didn't write out a proper pattern for it - just notes.
