I came up with 2 easy designs that used the squishy Daruma Genmou yarn which is DK weight, a pullover, Wadachi, and a shawl, Minamo.
The yarn was such a pleasure to work with that I will definitely use it again in the future. Perhaps knit myself the Wadachi sweater. (I had to knit the sample in a much smaller size than myself, and the company got to keep the sample as we'd agreed :)
If you have not checked out their yarn, you should it's quite a fun yarn. It's slightly squiggly with a thread that runs through the center.
