Thanks Ingrid. But no, it doesn't seem like one decreases until the 9th. row and it looks like you add stitches on every odd row. But if I understood the rnd 1, I would understand the rest. The shawl is rectangular. You are suppose to start with one of the short sides and the instructions are:
[*P2, yo, ssk, k1, k2tog, yo; rep from *to two sts before marker, (there is a marker for each corner and this is the end for the first short side), P2, sl marker, work row 3 of chart, sl marker] 4 times.
Row 3 of chart is : yo, P, yo
Sorry for this long explanation but I am desperate. Thanks again, Maria
