If I recall correctly, I had noticed that I had a variety of autumn-colored leaf-print fabrics in my stash and sewed up several maple-leaf blocks. Then, of course, I had to go get the right background fabric — I tend not to have much in the way of yellow fabrics.
I didn't have a design wall back then, but the quilt is small enough that it didn't matter. I probably just arranged them on a table more or less the way I wanted them, and then proceeded to add appropriately sized yellow strips, trimming as necessary as I went along.
Before adding the scrappy binding, I marked the top with a simple leaf pattern, connecting the individual leaves with short curved lines to create a "vine-y" look, and hand quilted it with contrasting brown thread.
