Yes

Yes, you can. In fact not only are you able to play multiple Excuses in order to get out of a particular project…most of the time you will have no choice BUT to use more than one. If you happen to be the lucky player with a hand full of low point Excuses, you most likely will find yourself stringing your small Excuses together in a wild story of doom and gloom of how you couldn’t possibly do that particular Project. Even if you have to burn most of your hand in order to get out of a particular Project, sometimes it worth it to keep your point total low. When the turn marker comes back around you’ll start to build your hand up again, and you never know, perhaps fate will smile fondly upon you and just give you a small Project to cope with next time.
