People that made it found it was way too big as written. Try a CO with about 88-96 sts and when it gets to half the width (length?) you want, start the other half of the pattern, picking up the short rows.
Well, it starts with 5 rows, and tells you to repeat the 5th one 15 times, then 17 more, so I guess you’re right, I was going from memory (something I should have learned NOT to do a LONG time ago!:shock:) and I made a mistake.
I did make a swatch before hand and made sure the yarn was the right weight. I’m just using Red Heart Supersaver in Bay Print. It’s variegated shades of blue to beige. Very cool.
