Hello all I jsut have a question I know that I have asked before but I just don't get it... I need to start a new ball of yarn.. I don't have wool so I was told to just overlap.. I don't really understand could someone please explain.. I saw the section that Amy has but I still don't get it..

Hold the thread you have been working with and then place the thread from the new ball against it, you can see that in the picture of Amy holding the thread. All you have to do is knit with BOTH THREADS for a few stitches, then drop the old thread (yes, just drop it, you'll weave the end in later) and keep knitting with the new. Et voila!
