An article on how to read a Japanese Crochet Pattern. The center symbol that she translates to "make 2 loops" is the "magic ring/loop." (If you don't know how to make it, it's easy to find via google.) Remember: Japanese and US crochet chart symbols are the same. UK (British) symbols are slightly different.

Clear explanation of crochet symbols
This is the symbol instructions for the Ripple Crochet. The multiple is 12 + 6. The center valley sections are a double crochet decrease. It is done by doing half of your double crochet, leaving two loops on your hook. Skip the previous decrease and continue with the other half of your decrease. You should have three loops on your hook. Pull the thread through all three loops on your hook to finish the decrease.
