My first job's company logo came to this squash racket case.
As at all panels made from several pieces, I made them a bit bigger. I cut out the final shape after sewing them together - this way the little inaccuracies that always happen (and accumulate with every seam) don't matter.
It can't be ironed - the seams between black and orange must be flattened by two lines of stitches.
I started sewing from the corner because there I wanted the seams to match exactly.
I joined the other sides of the zipper and band just before I ended up sewing the edges.
