I've just finished the first quarter of my own version of this quilt. I've been working on it on and off over the last few months, and some of the information I got from earlier posts here was super helpful, so I thought I would contribute what developed from that.
I'm a fine art student vaguely specialising in textile design, with a view to work in prop and costume for film, so this has really been a side project for me outside of studies to go into the portfolio. Because of that, I've been trying to make it as screen-accurate as I could. It was based mostly on the images found on this thread (you guys are all great!) and some maths to get the various dimensions and the slope of the cone right.
Most of my close up detail was based on one image in particular posted earlier, and I'll explain that before I show any close-ups of my own. Hem lines can clearly be seen between each segment, as well as around the orange triangles, most obviously at the base. I highlighted this in yellow underneath, for comparison. Very faintly, you can see the edges of the orange aren't clean - there is some fraying. I've circled where this is clearest in blue.
Because of this, I have tediously sat and cut out hundreds of reinforced black triangles, as well as hundreds of rounded orange ones with no seam allowance. I'm aware Neoprene was mentioned earlier on, but I'm not wholly convinced by that. Firstly, the cost of that would be immense on a film which had a relatively small budget, especially to spend on one prop, considering too the tools that would be needed to heat seal it etc. Secondly, the fabric in the image simply doesnt look like neoprene. Neoprene is much much thicker and spongier, it wouldn't behave in that way, with visible bumps and wrinkles and shallow seam folds. I could well be wrong, and I welcome anybody to conjecture as such, but I have some modern neoprene scraps I'd be willing to mock up samples with to demonstrate my reasoning. The logical selection both for them at the time and for me now based on these images is simple quilting cotton. It's pretty cheap (mine is £7.99/metre), comes in every colour under the sun, it's thin and easy to cut/sew and behaves like the fabric shown up there, and requires no special equipment to work with. On this basis, I've done mine as such:
Excuse all the loose threads, I've not had a chance to go round and trim them all up, especially the frayed ones from sewing. I'm not sure these were the best example sections, but oh well. You can see the pointed shape, and how I've gone around the inside edges of the triangles. I feel as though I should have stuffed them more, I only used one layer of the thickest wadding I could find, and it gets squished down quite a bit inside the shapes. Also I'm fairly proud to say, the 'cones' invert in the same way they do in the film, when pressed down on!
The colours don't show up in these photos as well as they do in real life which is a shame. I'll post more pictures around the halfway mark, I already have most of the next shade of orange cut out...
