A PLTQ = poncho liner top quilt. PLUQ (under quilt for hammock) can also be made.

Poncho liners can be found at army/navy surplus stores for around 20 - 30 bucks.

I cut mine and did in fact sew grosgain around the edge because it is rather larger than my needs (I am a small dude at 5'6") and I wanted to save weight, but you don't have to.

There are strings around the perimeter, tie the bottom strings together till about 24" from the bottom to form a foot box. walla, a top quilt good to around 40 degrees pending on if you are a warm or cold sleeper. 40 has been good for me thus far.
