12" and just over 1/4" ... phooey
THIS is why I made a "practice" block.
It's part paper pieced and part strip pieced. The strip piecing is easy and I measured the FINISHED strips, then I measured the sub-cuts, and measured the finished sub-cut pieces. No problem. I had measured the 1" test square on the paper piecing part - so that should have been correct.
But when I sew the sections together ... I'm just shy of a 12.5" block and this is WITH my 'scant' seams!! I'm always careful to test that my 1/4" seams are measured AFTER I iron.
I may go ahead and try to make this block with the F8 I received (my practice block was made of all my own fabric) and reduce my seam allowance ... I'm going to think about it.
I'm gonna go play with my dog.
