The Costermonger by Merchant & Mills


The Costermonger is the essential market tote designed as a backpack. Fill it up with wholesome goodies, leaving your hands free to tickle your dog. This is a simple satisfying sew that uses little fabric so ideal for using up some of your stash or making as a present.

Also available, the Costermonger kit which contains the hardware and leather straps used in pattern.

Skill level: Beginner



Suitable fabrics: oilskin, dry oilskin, mid-heavy weight cotton canvas or drill, mid weight denim (8-14oz). 

All seam allowances are 1.5cm unless otherwise stated.

You will need: 

  • Leather Strap Version: 
    • Rivets 9MM x 8.
    • Metal sliders 1″ x 4
    • Leather Strap 1″ x  2 (if you are buying our leather straps they come about 145cm long so you will need two of these). 
    • Matching thread.

Note: When inserting the rivets we recommend using a very solid surface like a cement floor so there is no movement. You will just need a hammer to set the rivets, but you will need something to make a hole in your leather, like  a revolving hole punch. 

  • Webbing Version:
    • Metal sliders 1″ x 2. 
    • Webbing 3CM wide x 1.6M. 
    • Matching thread.
