I finally found a decent detailed Finished Object photo of my current major work-in-progress..
Lo and behold, the photo indicates I goofed up a major detail about six rounds ago. Can anyone say “frog”? Good thing this discovery was made before I proceeded any further!
Contact with the poster of the photo resulted in sharing the CHART!!! for this blanket. Perhaps now I can get past round 11 without tearing my hair out.
