Further Instruction Needed

I've been working on a tatted snowflake. All was going reasonably well, right up until the end. I then encountered a couple of tricky joins that had me backtracking and retrying, repeatedly, and perhaps shredding my thread to the point of no return.

Those two yellow pin heads are at the locations that need to be joined. I'm now in the process of asking on various tatting forums for help. Are you surprised that there are several? I've been pointed in the direction of several YouTube video tutorials that should be helpful. Not as helpful as having a real life instructor sitting down with me to take me step by step through the process, but a step in the right direction -- I hope.
