Feline, what are your thoughts for the quilting? Is there a particular motif you want to use? There are several different kinds of quilting and the layout might influence what you are going to quilt. What is the use of this quilt? Is where it is going very structured? if so, you might be better with the more defined shapes (triangle/diamond) if the spot where this is going is more "free spirited" then the random one might be the better choice.
I can actually see the different types of motifs I would use to accent the shapes, for the random I would do a smaller triangle design. For the large diamond shapes, I would quilt a motif big enough for each diamond......same as with the large triangle
Now that I am thinking, I would love to try some big quilt motif for each of the diamonds....something dramatic
Might have to put that on my "to do" list in the future
