First of all, thank you to everyone who replied. Your responses made me slow down a click and take a closer look at the project ahead. I have decided to place the 'buddy build' (that's what I'm calling it) on hold for the time being.

Per Charlaine's advice, I found an old fiberglass rod which was just lying around, which was also missing a guide, and grabbed a spool of cheap thread. I put the bobbin in one of my fly tying bobbin holders and tried to walk my son through the process of wrapping the guide onto the rod. As you can imagine, it didn't quite goes as I'd had hoped. So, we're gonna wait a bit until he's a little older.

Debating whether I'm going to try my hand by myself first. If so, any suggestions on a good starter kit? Is it worth it to spend the extra money to get a better kit than the Forecast?
