I bet you can guess. Right there in the fabric itself! I loved that uneven grid in the borders as I was sewing with it, so it made perfect sense to mimic it in the quilting.
Now most of the time, I choose a quilting pattern that reflects the design of the quilt in some way, and sometimes I go with an 'overall' geometric design that just feels right, like organic or straight-line quilting or a grid. So it's a treat of sorts when I can pull a design from one of the fabrics.
Here's another example of that, in my mini Still Swooning.
See that black square in the center of the quilt? The quilting design all came from that, and I shared about it in more detail in this post, if you're interested.
So just a reminder that there's more than one element of a quilt that can influence the quilting you choose to do. What do you think influences you the most?
