I'm getting ready to make my first underquilt (climashield) and have read as much as I can find in the forums. I'm a novice thread injector. I've made a few compressions sacks and a top quilt so far. I am currently trying to decide between making an KAQ (guide)or a simple rectangular uq modeled after this thread. Based on my skills and the estimated time from each quide, a rectangular quilt looks like it will take less then half the time to make.
What are the advantages of going with the KAQ pattern and do they outweigh the extra time and skill required? Do the straight rectangular quilts perform significantly worse then a KAQ style uq?
