Hi all,  really making progress with some foam based patterns, however I'm still having issues with air bubbles forming when covering the foam pattern with woven cloth for strength,

can anyone suggest where I'm going wrong? I've tried laying down the resin first, and I've tried wetting the cloth from above - but still seem to end up with airbubbles that are near impossible to shift even with a bristle roller - I also have issues with the cloth lifting in corners Sad  Would I be better with chopped strand?

Many Thanks,

James
