I needed two attempts to get it right. My first attempt was slightly off due to a couple of blocks being a fraction too big (it all adds up in the end) so I unpicked it, fixed up the blocks, cut new sashing,
and went through the sewing, trimming, checking, marking rigmarole again. I was fairly confident that it would be right this time because I didn’t have to stop and adjust anything, just kept sewing and I was
right, when I turned it over the sashing strips all matched up well enough to satisfy me. Triangles next week.
