Thanks for the links.

Struggling to find a settled position for a concert acoustic. [br]Tried a guitar rest but a big fail.

Settled for between the legs angled off the left leg but the bout resting on the right and supported by a strap. [br]It's almost a case of deciding where you want your left hand and find a way to get the guitar there, not the other way round.

Tonight I just raised my left leg until the fretboard felt right, then I played with the height of the footstool to support the left leg. [br]Did seem a way to get that comfortable, correct posture position. [br]Also deliberately positioned the stool so my square position was to a corner of the room so I could quickly check I was staying square.
