I'm working on the Flower Basket Shawl and have a closed-ring marker before and after the Center Stitch. There is a YO before the first marker and a YO after the second marker. So it looks like this: YO - Marker - Center Stitch - Marker - YO. I suspect that there's something about those YOs that caused the yarn to go THROUGH the Marker while I was knitting the next row above (purl across). I just can't figure how it happened though. :( Any ideas?
You can see two strands of yarn going through the ring marker on the right side.
