This isn't "it", either, but does give some ideas:
The Bedroll
In contrast to the men who wore the knapsack, were those eager to discard them. Some evidence suggest that most soldiers belonged to this latter group. The Blanket Roll began to immerge as a substitute for the knapsack to those who found the knapsack a galling piece of equipment. The advantage of the blanket roll is it is lighter, and tends to not put as much strain on the back. The big disadvantages are that the contents that can be carried is greatly reduced, those contents become scattered upon unrolling the bedroll, and it can greatly increase an already intolerable temperature.
The words of the soldiers best describe the blanket roll. A member of the AoPs 9th Massachusetts Infantry explains: The inventive genius of some produced what was termed the horse collar . An Army blanket was spread on the ground, and a few necessary articles of clothing from the discarded knapsack were spread thereon; then the blanket and its contents were carefully and tightly rolled up, the ends brought together and firmly tied. This singular roll was put over the head and rested on one shoulder and against the opposite side under the arm; in this manner it was easily carried. When tired of carrying it on one shoulder, it would be shifted to the other. At a halt for a few minutes it was used as a cushion to sit on
It was found to be a great relief from the much despised knapsack with its cutting straps and awkward, back heavy burden.
The Confederate Prisoners above offer an illustration of soldiers wearing horse collars of different sorts. One has what appears to be simply his rubber blanket, rolled with a twist, then slung on his right shoulder. In the center of the photograph, we can see two soldiers wearing blankets folded into a horse collars, then slung from the left shoulder.
I would like to note that, had the soldier reduced his knapsack load to the items he reduced his bedroll to, he easily could have continued to carry his knapsack.
A soldier in the ANV recounted, I had a very good oilcloth haversack to carry my rations in, a tin cup, a rubber cloth, a blanket, a pair of jeans drawers, and a pair of woolen socks; the socks and drawers were placed on the blanket, the blanket was rolled up with the rubber cloth on the outside, the ends drawn together and fastened with a short strap.
Another method of carrying the bedroll, termed the hobo roll was to roll the blankets and extra necessities into approximately a 24 inch log roll, and then tie a rope around one end, then the other, leaving a u shaped length of rope that could be slung over the shoulder allowing the roll to rest in the lower back. This method allowed the soldier to carry the roll with out added bulk, and heat, in the hot summer months.

I was once advised by a "Man of the Road" to obtain (one way or another)
3 furniture pads/blankets from a moving co. and sleep with two down and
one over me, once I had a dry, safe place.
Heh- I hope this wasn't too far off. Or too long
