No I just looked on Pinterest and then made it up.
@Efemera I may have inquired previously but don't recall a reply if I did. The brain is currently over everything.
Please be a dear and give us the rudiments again. I think it's coming back to me. Did you sew strips together then cut your wedges? Was it 1½inch strips? Am I thinking of something else? Hmm, that would be good with longer strips. Did you draw the triangle on paper then grab pieces long enough to cover, stitch together then trim? Or did you.....
I'm sure there's more than one way to get to done with this.
