For those that do a floating liner, do you just stitch the inner bag to the other bag along the top seam and then put the binding around it or do you just put the binding on at the same time as you joint the two bags? Is there anything else used to support the inner bag or is it just the seam along the top of the opening? Also, what do you usually use for inside dividers and pockets? Do you guys just use cordura or do you use something lighter? I would love to make a bag and am interested in some of the details. Thanks.
