I will get around to doing that, Charlotte - thanks very much. But I'm actually forging ahead with my mat (yes, that's what I'm making, would you believe?) with its open-weave look. I would've preferred for it not to be like that; but the fact is I need to have it available to cover several places on my bedroom carpet where, when I swapped the bedroom with the office, there are some strips of the original beige carpet showing through the current chocolate...
And DCM, thank-you for confirming my strongly-held suspicion that in the .pdf of the pattern, the stitches shown simply cannot result in the accompanying photos.
