Welcome to the Quilting Board MarDar! .... from Southern Ontario, Canada
Oh my .... how I do like this one!
Great pics in the link to tempt one showing some variations.
Especially the final pic/link.
I'd test make one block (four template pieces together), or even four sets to see how much of each fabric I used. Then use that to estimate for the size of quilt I wanted to do .... adding on some extra!!!
