It's a paper-pieced pattern. I don't think I have done any paper-piecing since last year. And I didn't enjoy this pattern at all! I think it looks nice, but this is version #2 because the first one had hideously mis-matched points all over the show so it went in the bin. And in places this one is just over 12.25" rather than 12.5" - which I know will work out in the seam allowance - but it was a fiddly pain all the same and not a block I will ever sew again.
