I was having trouble with the first try at Olga, the blue one, at rows 19 through 21, so I started the second try, the red one, to better understand how to do this amazing pattern. I almost gave up on Blue Olga, but really it was too pretty to give up on, and as I did Red Olga, I realized that Blue Olga is accurate with the exception of one extra sc in one row. Red Olga has no mistakes at all. Loving this pattern!
