I am planning on making a underquilt based on the KAQ design, my hammock is an extra long DIY speer (about 11 inches longer than a standard speer. My question is..........since my hammock is longer, do I just add a foot to the standard KAQ design? If so, do I leave the end width approximatly the same as the origional design? Also, since my speer isnt asym, what about changing the KAQ design to more of a balanaced diamond shape? Any suggestions?
