There was a class offered for these through our guild last year. I was unable to participate as I was out of town. The ones who did this one (there were 2 patterns offered) that brought them to show and tell said that they were glad they had done a class and that once they got the hang of it, it wasn't difficult as long as they kept going. Those who set it aside to finish weeks - or more - later found it hard to figure out where they'd left off and to get comfortable with the process again.
Remember, of that 40 pages, part of it is the templates, lol! So maybe only 30 pages to figure out.
I have the seasonal table runner pattern, but haven't attempted it. Yet...
