***BOOKENDS*** 

2 CANASTA

You must have 4s and Aces melded first (Like Bookends) 
before you can meld anything else. You can meld the 4s 
and Aces together or on different turns. Once you have 
the 4s and Aces melded you must wait until your NEXT 
turn to meld anything else.  You can make a canasta of 
either Aces or 4s at any time. You may pick up the pile!
