So I did some shopping.
The first thing I found was this fabulous eye chart-inspired piece. I love the vintage feel of the chart, combined with the knitting references. At $20, it seems like a great art piece for a reasonable cost.
Next is this great Red Cross poster. Also $20, I love the old-school war propaganda look, and the colors are fabulous. Not to mention, the yarn looks luscious.
Or, you could go a little more three-dimesional. I've seen about fifteen million yarn-wrapped letters on Etsy and Pinterest, but I really love these yarn letters on Etsy, which are wild and interesting, and could make a great wall installation.
I love yarny housewares! Do you have anything on your house/craft room walls that you want to share?
