Personally I haven't been using my book. I go into the DJ computer program block chart and click on the block I want. Make note on how they do it. THEN I go to the internet and type in "dear jane b7" (or whatever block I need). There are a number of blogs that have easier or different ways to make a block. Then I make my block.
This way has been working for me so far, but I've only done about 10 or 12 blocks so far.
