I bought a metre of the polka dots at Dressew in Vancouver this summer with a 2+2 skirt in mind for Kate. The selvedge says it's Sevenberry from Japan and is a linen cotton blend. It's quite hefty and didn't really soften up with washing (although I only washed it once). It was a slight splurge and the flounce didn't use the whole metre so that made me pause a bit; I like to make the most of "special" fabric but I couldn't get this dress out of my head so cut into it. I'm sure I'll find some way to use up the remaining odd piece.
I've made this dress before and found the facings were a bit of a pain when it was worn so I omitted them and finished the top with bias tape. I also doubled the width of the strap so that it would meet the school dress code.
I love it and I'm glad it's out of my head and in the world. If K. wears it, that will just be a bonus :)
