I worked around it, but you had to download the viewer to see the pattern in PDF.
One question though, why does it have you sewing 2 large triangles together before adding the little one? It is totally not needed and a waste of fabric. It seems to indicate the stitching line is through the center of each triangle. Why wouldn't you just do one layer and when you put everything together run the topstitch through the whole table mat, and around the egdes.
It seems to suggest that the only tack downs are through 2 layers of the triangles that aren't needed at all. Hmmm!
Plus the fee for this pattern is $8.00.
