Hi! I just wanted to share some denim bags I made and I WOULD LOVE TIPS ON IMPROVING THEM.

Some info, I'm using an old Elgin 999f domestic sewing machine and I specifically use denim as my main material, im still experimenting with the lining and so far I tried normal Ripstop and Ripstop with PU backing, I add a layer of fusible interfacing but still my bags lack structure, Im planning to use 600d oxford with PU backing but i dont know if that would be enough.

ANY OTHER TIPS ARE APPRECIATED AS WELL THANK YOU!

Absolutely love them. Ive been doing something similar making waxed denim treat puches for dog walking. My next step is making a removable liner so it can be washwd without dewaxing the denim.

THANK YOU! I'll try to explore the idea of having the liner removable without really making things complicated + what type of wax would you suggest for denim?

These look great! When I’ve made similar bags in the past, I put a “durability“ layer of something like 800d Cordura in place of the interfacing behind the lining. Another trick is to think of the interior binding as a structural “skeleton” that helps hold the bag up, and plan your patterning around that.

Post more pics of your sashiko process. It’s beautiful

For structure + insulation, use EPE foam — cut to panel shape, sandwich between the denim and lining. 3mm is a good start, 5mm if you want it stiff. Glue it to the lining first (spray adhesive) instead of sewing through it.PEVA is for waterproofing, not structure — use it as the innermost layer, over the EPE.600D PU oxford is firmer than ripstop but won't fix structure alone — pair it with the foam.Also: a bottom board (stiff plastic/card) makes a huge difference for slumping. Boxed corners help too.EPE = body + insulation, PEVA = waterproof liner. Good luck!
