Round 2, Continued: There are already 9 chs completed.
Sc in 4th ch from hook.
Normally, if working a row of sc, you wouldn't leave so many extra chains; in many cases, you'd probably work into the second chain from the hook.
There's a reason for leaving extra chains here. It creates a small hole. The hole is not big enough that it will be noticeable in the future when you're gazing at the completed flower. Notice that you can't even really see it in my photo. It is, however, big enough that you'll be able to insert your crochet hook through it when you reach the appropriate spot in round three of the pattern.
