I am building a custom Winston ( dark emerald green ) fly rod. It will have black nickel hardware and the reel seat inserts will have green and brownish tan color. It has been suggested to me to use a wine colored thread on the build. At first I was thinking “really?”, but as I thought about it the wine color sounds interesting. Does anyone out there have any thoughts about this color scheme?

Only you can decide what looks good to you. Thread is cheap - try it. At least wrap a bit on the blank and wet with alcohol - or better yet soak with some epoxy to see then wipe/pull it off. Do it in a section to be covered by the grips if concerned

Garnet on dark green looks good.

I used the ProWrap Merlot color thread on a small 2wt fly rod, natural graphite color, I built last year and it came out great. Added a little white tip to the lower wraps In a nod to the white tips on a brook trout fin.

I agree with what’s been said above, to a few wraps and see how you feel about it. If you like the looks, you have your answer.

Thank you for your responses. I have done the trial wraps many times before and was more curious if anyone had ever used that combination before and what they thought about it. I have been building rods for about 18-20 years now and have read up about many different topics over the years on this site but never really posted anything, so I thought today why ask as there seem to be a lot of very knowledgeable people on this site!
Again, thanks.
