Fretboard Inlays

The markers on the side are enough so I know where I am on the fingerboard (while standing at leats) but kind of similar to what noteboat brought up...

At school I help teach a guitar class to fairly young kids and I recently started bringing in the Martin....It was hard for them to follow along on what frets I was fingering.

I just wanted to explore my options on inlays. I think for now I'll use some masking tape or stick on dots then later on ,when I'm sure about the inlays, spring for the real thing. The guitar will still sound the same either way :D I suppose thats really what counts anyway.

Thanks for the help and advice, everyone
