I can do some of my other fabrics in the tapered shape, but as the pattern needs to be cut as an arc, it won't work on anything that has stripes, lines or a 'right way up' that needs to be cut on a straight line. Get in touch and I can tell you if it's possible or not.
As an aside, I love this time of year. Peonies are my favourite flower and you can pick them up so cheaply at the moment. Have stuffed my house full of them.
