I made some ripples! Actually I don't know how I got the idea but as I finished the first one I thought they might fit quite well on my living room window still. So far I made one in white, one in red and one in brown and I'm thinking about adding some pastel-colored ones to my collection for Spring.
The yarn I used is Schachenmayr Bravo, 100% acrylic. And the pattern can be found HERE.
