My new kitchen has more cupboards than where I lived before, but not enough room to store bottles for the bottle bank and glass for recycling. Floppy plastic bags in the corners aren’t exactly an elegant solution, so something else was called for. I had a piece of very thick stabilizer, which got put to good use. I just made it up as I went along, using the width of fabric as the circumference of the basket. Then it was just a matter of dividing the circumference by π (pi or 3,14) to work out the diameter of the bottom (yes, I'm such a geek - but try it, it works!). The lining was just made like a bag with boxed corners.
A bit of heavy going working this huge thing through the sewing machine, but other than that it all came together quite easily, and it makes for a much prettier form of storage than a plastic bag, right?
