Thanks for the help, particularly about the direction of the fish. I think I can convince myself of the logic of water-currents and fish swimming directions, but if I can't I have a fair bit of fabric and could always take my chance with the bias!
Actually, could it be interfaced with really light fusible interfacing to prevent stretching, or would it be better to leave it to chance and sew carefully?
And I probably will go with the on-point style, since that was what the pattern I'm working with called for anyway =)
I'd take a chance. Don't press/iron until it's sewn in place and pin really well before sewing carefully. Your side setting triangles will be your biggest issue since they're not entirely enclosed til the borders are on. Press very carefully there. ;-) Finger press then use your iron in an up and down on the seam only motion instead of sliding it over the fabric. Good Luck.
