Making a loop directly on a fly line

This is a way of making a loop on a fly line that will give you a very neat and tiny loop and a smooth transition between the different parts of a rig.

This is a way of making a loop on a fly line that will give you a very neat and tiny loop and a smooth transition between the different parts of a rig. The loop is very strong and actually quite easy to make. You will need a threader of the type that is normally used for getting tying thread through the tube of the bobbin holder. It has to be the type made from metal thread (piano wire) - the ones made from thick monofilament will not do.

Try this at home
Start doing this on an old piece of fly line or on the reel end of a new one. Not all lines have the hollow, braided core needed for this and you might fumble the first time. Spare the front taper of your favourite line till you have some practise.

  1. Dip the end of the fly line in acetone (nail polish remover is the same, but more expensive) for 10-30 seconds
  2. Remove the softened coating from 5-8 cm (2-2 3/4") of the fly line, revealing the braided core
  3. Stick the tip of the threader into the core as close to the coating as possible
  4. Pass the threader throgh 2 cm (3/4") of the core and push it out through the line again
  5. Thread the tag end of the core into the threader
  6. Pull approx. 2 cm (3/4") of line into itself and form a sufficiently large loop (secure the loop with a thin pencil in necesarry) and remove threader. If the tag sticks out of the side, cut it as close as possible, and pull the rest into the center of the core.
  7. Apply a little Aquaseal or similar on the braid, reaching from the coating and to the base of the loop. Smooth it with wet fingers and let cure for 24 hours.
  8. The loop is ready




Nothing worse than a know all!
I am a novice fly man, although I have fished for years, and welcome any advice to put trout on the bank/in the back of net....
We all have to start somewhere, and thankyou so so much for taking the time to help us newbees !

What a surprise to find this page. I have been doing fly line loops in the braided core this way for many years after inventing the method myself. I have never come heard of anyone else doing it this way. Great minds think alike! The only difference is I pull 2cm of the tag end through and coat this in glue, then pull it back inside the core. Just to be sure, you know. I also do twined leaders that naturally form a loop at both ends so this joins straight onto the fly line loop. I hate comercial braided loops as they are much more bulky but have a place on lines without the right core. Ps Have you tried welded loops or welding a braided loop into the fly line coating. Use clear heat shrink to keep it all together but remove the heat shrink once its done. It's pretty neat and easy to do but not as neet as the method on this page.


Funny that I founf the convaluted answer to be more helpful than the description of the running line and "any thin line you like"...

Wayne...I'm interested inb how the epoxy has held up.

I was putting on one of the flyline leader loops ,the one that is made out of braided mono and uses a heat shrink tube,I inched the loop on all the way and installed the shrink tube half way on the loop and half on the flyline,I used a heat gun to shrink the tubing,when I reeled in the line to the reel my finger caught the edge of the tubing, it pulled the whole loop and tubing off the end of the flyline,at this point I did not trust this connection,so I installed a new loop and sleeve but this time I put some flexable expoxy on the loop and line area where the line and loop meet,then slid the shrink tubing over the expoxy half way on the loop end and half on the line,heated the tubing to shrink and when the expoxy oozed out I wiped off the excess,let dry, this connection cannot come off it is very strong.

Convoluted, long winded... maybe, but honestly: if you know so well, just don't read it, and leave it to people who are less experienced than you to peruse this information. You might find it banal, but there's a reason why these articles are the most read on this site.


I have never seen such a long winded and convoluted explanation in all my life. All you have to do is choose a line 2# or 3# above that of the rod rating #. Try casting it first to find the point where it loads the rod from the top ring, mark it with a pen, check and double check it, then make the cut. Once cut to the size that suits you, attach a running line of your choice. This can be a purpose made line, braided or nylon line or any thin line you like, your choice - job done.
