Hi and welcome.
Here is another that is just great.
www.netknots.com
There are very small number of basic knots for fly fishing:-
Leader to line
If you are using a loop, then learn how to tie a Perfection Loop in the leader for attachment.
If you are making your leaders, then learn about blood knots a water knots
For tying flies to leaders, the leaner about the improved clinch knot or uni knot
If you are using droppers, then learn how to make a dropper loop.
Leant them so that your do them without thinking and you will be able to cope with all situations. Cheers
