I have a question regarding tumbling blocks made with strip-piecing and no Y seams. I also saw a grandmother's garden quilt made up of lots of hexagons that also use the strip piecing method with no Y seams.
However, it looks like both of these end up with vertical seams going right down the middle where you join the strips.
And then your tumbling blocks with have an additional seam going down them.
Would love to hear comments.
