Just for experimenting, a standard twin sized blanket is 60x90". The quilt wide sizes I've seen are generally 55-58" wide +/- . EE Revelation is a little wider - 54" standard, 58" wide, and 64" extra wide. Their lengths are 78" standard, 84" long, and 90" extra long.
So, an X long, X wide Revelation is about the same as a twin sized blanket. You can lay on the floor and see how it drapes around you. Of course the loft of a quilt will likely make the effective width a bit less.
Its possible to make a synthetic quilt in 1-2 hours for well under a hundred bucks.
You can get a twin sized comforter on Amazon for under $30. It might be a tad wide but that can be trimmed off if you want to experiment.
If you're good with a sewing machine, Amazon has 750 fill goose down for $26 for 1/2 lb. An X-long, X-wide Revelation has 26 oz of 850 fill down. $52 for 1 lb of Amazon's down will give you a 0 degree quilt. Of course, quilting with down isn't as easy as it sounds.
