Those are beautiful! I like the one that's in honor of you grandmother the best of all!
You do beautiful work! You said that you used paper templates, I never heard of the Mylar ones so I just read the tutorial from the link. Did you try them too? I have the paper pieces and a whole box of basted ones but haven't worked up the courage to start sewing them together. I don't know what kind of thread to use...then I don't know what stitch (whip stitch, ladder/H stitch, buttonhole stitch, which I saw on this board last year).
Did you sew them together side by side as she does in the tute? I never would have thought of it.
I agree with others about blue between the flowers (my favorite color). It would lik pretty if the blue areas were shaded from edges to center.
Thank you for sharing! I'm inspired, will look for that box of basted pieces...
