Good idea. Daniel has been working on that for a few weeks in his spare time. We'll get it going at some point. The hatch chart will show the fly when you mouse over the name, then you can click and go to the online catalog to buy the fly.
The problem with fly tying materials is availability and the quantity of units. Most tying suppliers are often out of items. It would be hard for us to keep track of what is in stock and what is not. I think we have around 5,000 items in the fly tying department. I don't know if we will ever do that.
