Very pretty ... keeps the eye moving.
I just had a "light bulb moment". If you have access to a copier, lay your fabric on it and make several copies (b&w or color; doesn't make much difference). Then, using the template, trace around various placement options for the blades, cut them out (perhaps 5 of the 10)and arrange them so as to give you an idea of what your finished kscope would look like and go with the one you like. If you're one who is "fussy-cut challenged", this little technique could save some time and frustration (i.e. would like to know how it would look before I cut into the fabric) .
Disclaimer: I haven't tried this with this particular block / project, but I think I will. As I said, it was "light bulb momonent" as I was reading through this thread.
