Apparently I can’t read a pattern, and accidentally worked the transition chart before the butterfly chart. Didn’t realize until I was well into it - but I liked the way it looked so I left it.
I only worked the Butterfly chart once.

To do my mods:

• Work flower chart as written
• Work transition chart (you will have one extra stitch on either end)
• Work butterfly chart (first row will have to be fudged on either end) just once (entire chart)
• Work transition chart and edge chart as written
