>>779302Honestly super simple.
I ordered from ripstopbytheroll, they have nice fabrics for cheap.
Since it was my first try, I ordered 1.1 polyester fabric. About the cheapest stuff they have. I got it in black, they also throw in free guterman thread with every order which is nice. I used Apex 5.0 for the quilt which should be good to 30 degrees.
Again, I made mine simple, less cuts, less hassle. You end up with a slight boxier, heavier wuilt, but works great and covers well the way I did it.
Basically cut 2 identical pieces of fabric, about 84 inches by 52 inches. Then cut a piece of the insulation the same size.
Now stack them. Insulation on bottom, then one layer of fabric, then the other layer on top.
Sew 3 sides with the insulation facing down on your sewing machine.
Now sew about 3/4 of the last side. Then turn the quilt inside out. You'll basically have a square blanket now. Sew the hole shut you used to flip the quilt inside out.
To make the footbox I did a flat sew. Do the flat sew, then turn the quilt inside out (so the flat sew stitches are in the inside), and you're done. Pic related to show the flat sew on my quilt.
I can make one in under an hour.
