I have a couple of small canvas pouches that I am using for my car tool kit and wanted to mark which pouch has my SAE and which has my metric sockets.
These stencils are 120mmx70mm which worked out well for these pouches. I purchased these: https://www.amazon.com/dp/B0998YJP14
I used a Milwaukee Inkzall to mark up the pouches which bled a little but will be just fine for my toolkit.
The author marked this model as their own original creation.
