Narrative:

While issuing holding instructions to air carrier X I inadvertently said 11000, meant to say 12000. Loss of separation occurred. I then climbed X to 12000. Loss of separation occurred with air carrier Y at the holey intersection. This occurred after 2 sectors were combined due to thunderstorms over arrival fixes with numerous deviations and being put into a hold by new york approach.
