Why Keep Your Fly Box Simple
Starting a fly box can feel overwhelming. Shops show hundreds of patterns and gadgets, but you only need a small, sensible selection to catch trout in UK rivers and stillwaters.

How Many Flies Should I Carry?
- PTN × 6, Hare’s Ear × 4
- Adams × 4, Elk Hair Caddis × 3, Black Gnat × 4
That’s roughly 21 flies—plenty for a day. Replace what you lose, not the whole box.
Quick Setup Tips
- Match your tippet to the fly (4X for bushy dries, 5X–6X for small gnats).
- Start with a duo: PTN under an indicator, or swap to Adams when trout rise.
- Straighten leaders before fishing.
- Change with intent: switch fly or depth if no takes in 15 minutes.
Beginner FAQ
Do I need dozens of patterns?
No. The five above cover most UK situations for beginners.
What sizes should I buy first?
Start with 14–16. Add a few 12s and some smaller gnats for variety.
Barbed or barbless?
Barbless makes release easier and is often required on UK waters.
Will this work on stillwaters as well as rivers?
Yes—these flies catch fish in both.
