This was a quick make (well, 2 days because I'm a slow sewist) that was immensely satisfying because I got more practice with zippers, linings, and hardware and created a finished object that looks so good.
Pattern: Fremont bag kit (black waxed canvas and leather with brass hardware) with Pendleton exterior pocket expansion by Klum House. Leather Keyring kit in black by Klum House. Sewed with Gutermann polyester all-purpose thread in Black.
NB: The clarity and detail in Klum House patterns is seriously impressive. They anticipate problems and help you troubleshoot (like having a front pocket that's a little longer than the front exterior panel) and provide helpful tips to make the sewing process easier.
New skills: installing chicago screws
Lessons: Wool can be shifty/stretchy while sewing, so adding woven fusible interfacing will stabilize the fabric and prevent it from stretching.
A bi-level edge stitch foot (or a stitch in the ditch foot) are really helpful for making beautiful, straight edge stitching. Setting the needle position at 3mm will produce a lovely 1/8" seam allowance.
When boxing out seams at the bottom of a bag, pull out the fabric at the center of the bag to help align the raw edges of the box seam.
I got the best results with rivets using a regular hammer (heavier, so generates more force) and hammering on our crappy lino-covered concrete floors, and taking care to make sure the rivet was aligned vertically to prevent it from shifting / going crooked while hammering. Using a few light/medium taps on the lino sets the rivet without causing unsightly crimping from the post going into the cap.
3/32" punches are far easier to use than a 3/16" punch--the latter takes a lot of force to make a hole in 2 layers of fabric.
Use a bakelite mallet when striking the top of metal tools to prevent them from getting damaged.
The Klum House pouch was an excellent starter project before getting into the Fremont. It was a great way to practice all of the necessary skills before applying them to a larger (more expensive) kit.
When making a boxed bag bottom, an excellent technique is to mark the boxes, then sew the seam around the outside edge of the bag, backstitching over every box mark to strengthen the seam and prevent it from fraying while forming the box.
Fanning seam allowances (i.e. positioning them to opposite sides) is a great way to reduce bulk.
What I'd do differently: I maybe could have been a little fussier when positioning the front pocket so that I'd have a perfectly symmetrical pattern. (It was slightly longer then the front exterior panel, so I just lined up one edge and trimmed the other edge with the rotary cutter.) It's a very minor thing and really doesn't bother me.
Care: Spot clean
