My huge apologies to those of you who have struggled with the MC block - and thanks to Terri and Siobhan for bringing the discrepancy in the block, to my attention.
I have now had a bit of time to re-visit my diagrams and can see the mis-matched seams - my only excuse for this is poorish eyesight and bad counting - I miscounted a point along the chart when drafting on EQ and in my final quilt layout the discrepancy didn't jump out at me. I have actually had to re-draft all of the blocks for this QAL as my originals from class were all lost a few yrs back in a computer muddle.......hence my surprise Terri, and comment about my students not having had the same problem!
Today I upped the scale and felt sick when I saw the mistake - I am so sorry to those of you who are thinking they have gone wrong.
I have to say the blocks that have been completed so far don't look any the worse for the blunder but of course, we all strive for perfection in a block like this.
The pic below is of the completed block with matching seams and before the day is out will get fresh patterns uploaded to ScribD.
Almost at the last fence too! Trust me to fall.............
