Great advice! Thanks everyone.

Despite really really really needing a tool belt I've never made myself one. I'm always too busy at work or renovating my house - both places where I really need a tool belt...

So, a belt with detachable pockets/tool holders it is (over the top of the kilt.) I'm still pretty tempted to do a wallet/keys/phone pocket in the actual kilt though...

I have a bunch of russet hides laying about so the pockets and belt will probably be in leather over the top of the canvas kilt. I was going to deliberately age the kilt anyway and I might do the same to the belt and pockets. So it looks like I've had them a hundred years.

The off-center placement of the buckle is a great tip.

I have an old coin belt purse somewhere and I might copy how it attaches onto the belt (just two cuts in the back of the purse the belt slides through) or maybe strap hanger loops, or detachable loops on snaps or domes...

I will start drawing a few ideas up... pics will definitely be coming once I have something made up
