There are so many sensational bag handles out there, leather, vinyl, cork and more, this is how you attach them when they use rivets as the primary hold point. Enjoy!
Mark where you want your handles to go and rivet holes.
(The tool pictured is the Deadly Mojo Sewing Tools, Multi Mate)
Create your rivet holes and draw a line of glue (e.g. Tiger Glue) between the rivet holes.
Install your rivets.
Best shank length approx 2mm above the handle. This prevents twisting.
Use your favourite setting tool, hammer away and then enjoy!
