Personal Use only Fly tying leaders...

I am back to tying leaders. It helps me relax.

editing a leader formula then printing a label? is that possible...

I would like to edit some of the leader recipes to suit me and then print a label with the edits. Can I do that with this program?

Yes and no...


You can't edit the formulas (recipes) themselves. They aren't printed on the label, so that wouldn't make much sense anyway.

All the other things that go on the label are editable. They are shown in a form before you go the the "clean" labels to print them, and are divided in two sections: Leader info and Your info.
The First one is pre-filled from the leader you have chosen, but all fields can be changed as you please. The second section is empty, and there for you to fill with your personal details.
So you can essentially edit everything that goes on the label.

If you have special leader formulas that you use and that work well, you can share them by sending them to me. I can then add them to the long list of existing formulas. It won't make a huge difference for label printing, but will give you and others access to see variations of these formulas in the system.

Download vs. online...


I see that you might be referring to the spreadsheet for download, while I'm referring to the online system. In the spreadsheet nothing is editable. this is a very old system, which is not maintained anymore. Use the updated online system in stead. It's much more up to date:


Martin's Respones to my questions...

Martin thank you very much for the very fast response. I look forward to tying my own leaders and appreciate all the work that has been done to help us neophytes enter a new area of our very rewarding sport / pastime.

Enjoy the rest of your summer.

The GFF money box

… I have a small favor to ask.

Long story short

Support the Global FlyFisher through several different channels, including PayPal.

Long story longer

The Global FlyFisher has been online since the mid-90's and has been free to access for everybody since day one – and will stay free for as long as I run it.
But that doesn't mean that it's free to run.
It costs money to drive a large site like this.
