A blouse/tunic that started to have holes serves as a canvas. I have one front finished.
I considered working from the top down, but I have a pocket placed at the bottom (the dark maroon). So I'll be working from the bottom up. I can always add on other strips later, so length doesn't matter too much.
Sometimes I look at the fabrics and have no idea where to start. The trick is to begin at the easiest point of entry. In this case, the lower left edge seemed the most accessible.
Then I turned back the bottom of the blue, which was still unstitched, to get at the maroon and stitch it down.
