I used an upholstery fabric remnant and quilter’s cotton as the lining. I interfaced the upholstery fabric with a fusible cheapo non-woven interfacing. Between the nature of the upholstery fabric and the heavier interfacing, this bag is a bit stiffer than the first corduroy bag I made and carry around everyday.
There is no "pattern" for this bag, I initially came across a messenger bag tutorial on the wonderful Craftster site and just went with it. This tutorial is very clear for those not confident with their sewing skills. I believe the bag fabric remnant was just over 3/4 yard and 60" wide. You could adjust the bag size to fit any fabric you may have available. I keep the flap shut with a piece of hook and loop tape. You could probably crank one of these out in a day if you were really diligent. I am not, and took about three days of hit and run sewing.
This bag will be a gift for a co-worker, but I think I may make a spring-y one just for me to replace the sensible black cord one I’ve been toting around. Spring means new shoes and handbags around here baby.
