Here is the site.
I love this site. However, I can not read French. Usually just click around to get the files!! There is a picture on there of the towel, looks like it's right up at the edge. If anyone can read it, & just let me know where to place the edge of the towel, I'll be good! There's a line that stitches out first in the file so am assuming that is some sort of "mark" to place the towel??
I know this isn't the turquoise site but this has some instructions for the towel. Go to Freie Muster in the left column and then click the right arrow 3 times.

Maybe that corner shaped line is where you lay the edge of the towel? I'll try it on a cheap towel first! Tks! you did help, sewmom!
I think there are instructions somewhere on the blog. I'm sorry I don't remember where. All I remember is that the loop part of the design is done on WSS. Maybe WSS the whole thing?
I hope someone else comes along with more instructions for you.
