Making a simple leather tool bag for my bicycle that mounts under the saddle. Easy and relaxing project I was able to make in my apartment with limited tools in this lockdown period. Leatherworking is always fun and enojoyable to me! I decided to limit punched holes to minimum so I don't bother neighbours and got a decent result with drilling with 1.5mm bit and enlarging with thick needle/awl on the hand held drill. I used thick and un-finished leather for the side caps because it holds the shape way better than the thinner one I used for the rest of the bag.
If you are doing something like this you need to figure out a mount solution as most likely the way I did this is not applicable to all saddle.

For those asking where to find tools:
I bought mine some years ago when I was starting to make leather sheaths. I went for the cheapest I was able to find. Have been working great so far! Can't find exactly the one I have but I listed some in my amazon storefront that are pretty much the same and any similar ones will work aswell.
