    Hi Andrew, Don't creat vent holes. If you must, you can create a
    verticle slit in the mold beginning at the trouble spot and extending
    to the edge of your mold. It need not be more than 3mm deep and
    should be a clean slice. A wet surgical blade cuts easier than one
    that is dry. A hole will cause a loss in pressure and cause more
    problems than you have now. 

Have fun. Tom Arnold
