Feel free to send a direct message to me whenever you'd like. Otherwise, you can post whatever you'd like here as well. Or you could start a new "progress" thread in beardie tales or introductions. Now that he seems to be in the clear regarding the hornworms a mod may be able to move this thread as well. The benefit of posting to your thread is that you get the collective experience of everyone who reads it. There are a lot of incredibly helpful and experienced folks on here so that's not a bad thing at all. That said, I'll be glad to answer any direct messages you send to the best of my ability.

Keep one of the staples in there but try to mix it up a bit depending on what you can get fresh at the store that week.
