I just saw this video on Face Book about joining yarn that I wanted to share.   A lot of you are probably laughing, that I'm so excited about it, because you've been using it forever.  The link explains 5 ways to join yarn, the one I'm excited about is the first one explained, The Twist method.  This will sure make it alot easier, no more weaving in the ends.
