Hello

Many options, but for folk guitars without a neck heel button something like this is customary.

To strap or not when sitting is a polarising topic. I don't hold a dogmatic perspective on it and do both as I please acoustic or electric, so as [u]you[/u] please. Same with sitting or standing.

The [u]exceptions[/u] where I prefer to use a strap when sitting would be for Les Paul electric solid bodies with its imbalance idiosyncrasy and Dreadnought acoustic bodies which are an ill fit for me, and which the Yamaha F325D is.

Cheers,
