In the afternoon, the sewing teacher took me out to buy yukata fabric. I chose the design in the picture. It looks really neat with the fabric draped from the neck down, since the leaves of the tulips look almost like a river. It was, however, quite expensive. I can see how one might want to go with a plainer fabric like basic stripes that can be bought at a craft store much cheaper.
The guy at the kimono store also mentioned that most of his fabric is woven in Tookamachi. (He brought it up when he heard I had lived in the area.) They're pretty famous for their kimono. The store guy chatted about how Sapporo was a bit to far away to go for their snow festival, but he did make it to Tookamachi's snow festival once.
