Are you on the move or are you sheltering in one place?

On the move:
In an on the move scenario just wear a poncho and keep moving. When you are tired sit on the other one to keep your backsides dry. If you move too fast and work up a sweat you will be just as wet as if you had no poncho. Move slowly and deliberately, keep moving enough to keep warm but not so much as to get hot. You should be able to keep moving for the 2 days specified with small breaks for food, water and rest. If you have a place to get to then just get there and be done with it - you can dry yourself by the fire of the wood stove in your back-woods cabin once you get there.

Sheltering in one place:
You specified "woods" so you have more than just the ponchos you also have the material for a decent debris hut. Construct a smallish lean-to against a tree as skeleton, cover with the ponchos such that they overlap and shed water. This should provide something like 6 foot by 9 foot of rain protected area. Cover with debris to keep in place. If you can build a small fire at entrance you will keep out most insects and other nasties as well as provide some warmth. Push out all debris from within back to bare ground and you should be able to stay fairly dry. This shelter should be good for a few weeks but takes too much time to construct for an on the move scenario.

I forgot E&E scenarios. There are two -

1) "THEY" are actively looking for "YOU". Escape
This is the same as the On the move scenario above until you can convert it into the other E&E scenario

2) "YOU" are avoiding being noticed by "THEM" Evasion
This is much more the sheltering in one place scenario above with the additional burden of requiring camoflauge work. More debris on the hut, hut smaller and leaning against stone or large fallen log so-as to look more natural. Constant vigilance on footprints or leaving paths through the brush. No fires. Don't eat or relieve yourself near your hide, or in the same place twice. etc.
