I can't find this mentioned here so this is a tip I picked up from Nancy Watt when she was doing a demo on C & C.
When doing pyramage or stackers put on the foam pads and then use a glue stick on the pads. It gives you a chance to move the stacker etc in to place.
You don't have long but I find my efforts are better now.
I hope this works for you.:up::up:
