bylinesupplyco Report post Posted September 29, 2017 I am looking to make my first bag, and I am wanting to make a sort of Filson style leather briefcase. Anyone have any idea where to get a pattern for something like this, or how to pattern one? Quote Share this post Link to post Share on other sites

Fire88 Report post Posted October 2, 2017 Make your own Figure out what you want to put in it/how much stuff with room to spare. Get some poster board make a mock up, make changes as needed and remake the pattern with seam allowance if needed. Quote Share this post Link to post Share on other sites
