Apologies, I missed your question, so somewhat belatedly:Wow ,never thought someone had the same bag .How do you create a strap .would love to do it .love your bag
simply knot two twillies together in a loop (I use a silk loop to avoid marking the edge of the bag),
when the bag is open place the loop under the flap,
Close the flap, meaning you have a “strap” emerging from each side once the flap is closed.
Hope this makes sense?
