ISO sweater/wrap with wearing variations

I remember seeing a pattern that was basically a rectangle with buttons along at least one edge. By buttoning the buttons in different configurations, the rectangle could be a long sleeve shrug or a cardigan and some other variations. I thought it was from, but can’t find it there or at Ravelry. Does anyone know what I’m talking about and where to find the pattern, preferably for free?

See if this is similar to what you are remembering.

That’s it! Thanks so much!
