If you want to make a rucksack (backpack) then the PDF downloadable sewing pattern for The Atlas Rucksack is the one to chose. This unisex design can be made in any style you prefer. It features adjustable backpack straps and front closure straps, as well as a large front zippered pocket and top carrying/hanging handle. And the end result is a rucksack that is wonderfully comfortable as well as expandable and fully adjustable.
