The stilt walkers should be in their costumes and makeup 15 min before go time so they can start to stilt up and be already on their stilts with props in hands 5 min before go time so you can get them into position 5-10 min early.
They will need a bar height surface to use to get onto their stilts so we often request a table and 2 chairs be provided for this purpose- in which case you would put the chairs onto the table and help them get into the chair safely and be ‘ground support’ for them until they are in position.
After they are positioned, take some pics of them and then let them be – except check on them at least once per hour and bring water to them at least once per set.
If they have a break and a 2nd set it is your job to go pull them from the floor at their break time and to warn them of their break ending 5 min before it ends and then to bring them back to the floor.
