I am working on my first DIY project for my HH Expedition...an underquilt. I am going to be using IX as the insulation and only one side (the underside) will be lined with 1.1 ripstop. My design is based off of the KAQ design in the articles section.
Since I couldn't find any threads for someone who has done a KAQ with IX, I decided to merge the basic KAQ design with the IX design found here.
Below is the resulting design. This is just the basic cutting patterns, not the details such as shock cord channels, etc. This is my first attempt at doing any gear design...so please point out issues.
