The finished project ended up with a pad around 6'x23" with a rolled up width of a 11".
I went to Wal-mart and picked up two 4' straps to keep the pad together and be able to attach it to my backpack.
I have not had a chance to take it out on any extensive test but overall it look like it will last for a while.
This is my first instructable so any advice and input will be greatly appreciated.
