Idea to eliminate bubbles under top sheet

Hi,
tried to answer in viewtopic.php?p=35928, but it always throws me back to the index page.
So, I will try to press a cap with topsheet soon. So there is no way the bubbles can escape to the side once pressure is applied. Made up my mind a lot about dealing with this, but until last night no good ideas came to my mind.
But then, as always when I try to sleep, shortly before drifting off to dreams, a simple idea struck me:
If you lay up the normal way (layer by layer in the mold), you will always have the trouble that you will trap bubbles between the topsheet and the layer underneath (lets call it second layer for now)
So, why not alter this process a bit?
1) Put the top sheet flipped somewhere else, and put the second layer on top and roller these 2 together. Like this, all the bubbles should escape through the second layer.
2) flip this package again and add it to your layup. Like this, the bubbles will be between the second and third layer (e.g. the wood core).
3) Use rollers to get most of the bubbles caught between second and third layer to the sides.
In my case, the second layer is a thin fabric with a quite wild design.
What du you think about this? anyone tried already?
Cheers
