I have a small stash of Japanese fabrics which I use sparingly. It's really a good thing I don't live in Japan because we wouldn't eat and we'd live in a cardboard box because all I would want to do is BUY FABRIC over there!!! Anyway- I finally decided they needed to be used- so some simple infinity scarves were the result. The blue is I believe a Nani Iro- and the Black may be as well- I should keep notes on these I guess. The fabric is a double weave gauze which gives it the lovely drape.
The "pattern" is simply- fold the fabric in half lengthwise, right sides together and sew a 1/2" seam leaving a 6" gap for turning. You will have a tube- with each end open. Then,with the fabric still inside out, reach in to one end of the tube and pull it to the other end. Line up the seams and sew all around. Now pull it out through the opening, and slip stitch the opening closed- voila- took all of ten minutes!
These are the small size- one half yard, sewn the length. Large size would be 3/4 of a yard or even a yard- which would be a really long one to wind around. I use the entire width of fabric but you could make them narrower if you like. You can also use two different fabrics- use a flannel inside to make them extra warm. The technique is the same, just divide width in half and use two different fabrics.
If this isn't clear as mud PM me- happy to answer any questions!
