The person at Ziguzagu was wonderful.
I thought I would mostly have to figure things out myself. I told her roughly what I had in mind, and the dimensions.
She made a bunch of little sketches and came up with various ideas for how I could make the noren. She also worked out exactly how many pieces of a specific kimono fabric I'd need for one area, and the best way to sew them together, and then she cut all the pieces for me and made sure there would be enough seam allowance.
I had originally intended to use the sewing machine to sew the pieces together, and to sew the hems.
But when I saw how wonderful those chunky contrasting stitches and mending patches looked on the vintage furoshiki, I decided to try to hand-sew the seams and hems myself, if I can.
It might be overly ambitious and I might get frustrated and use the machine after all, but I'm going to try hand-sewing first.
