Hi guys, I am still learning and I have been using a small mould as a test.  I have just pulled my small money tray made of 2x2 twill carbon out of the mould and there are tiny pinholes on one side of the surface, I am sure that the bag kept full vac all the way through the infusion so my question is what are the main reasons for a pinhole finish. 

I have been working in the garage which is cold but have my mould on an electric blanket to keep it warm.  the only thing different with this infusion is that I didn't use any spray tack on the surface. 

I am quite happy to have these little problems as I want to learn as much as I can but I need to have an understanding of why things happen and how to improve.

Thanks in advance
