There is also the assumption that the shop owner is a knowledgeable fly tier and has tested various threads, and selected what is really in the best interest of the customer. Unfortunately that is rarely the case. The reality is that many fly shops carry what their primary wholesalers make available. Until about seven years ago, the two main thread brands available were Danville and UNI-thread.
Once entrenched in the store most owners are not willing to add new lines or change brands for a host of reasons, including investing more money in inventory and not having additional space to display the thread. At least five new thread brands have become available, all of which offer other options to what has been previously available. Are these brands better? The best way to find out is to purchase a few spools and do a comparison.
A little checking of mail-order catalogs will allow you to find them and a quick phone call will allow you to order a few spools and try them out. What is different about these threads compared to those that have been around for many years? Listed below is some information about thread which will increase your overall knowledge of this sometimes taken-for-granted material.
Denier is defined as a unit of fineness for silk, rayon, polyester, or nylon equal to the fineness of a yard weighing one gram for each 9, meters. Each has qualities that are more appropriate for certain flies than others. As an example all Benecchi threads are unwaxed and all Gudebrod threads are waxed.
Continuous filament threads are better waxed than unwaxed to eliminate fraying. Waxed threads are not essential to make dubbing easier.
All semi-twisted thread will flatten if the bobbin holder is counter spun right handed tiers. Author recommendations are based on extensive experimentation.
The threads are listed in order of preference. Size, strength, and color are all taken into consideration in making the recommendations. It makes sense to have a standardization, which would eliminate much of the confusion that surrounds fly tying thread today. His observations still stand.
So the newer Denier system is much better, right? No, not really! A true classic on the Danish coast and a very universal small fish imitation, which has not only caught thousands of sea trout, but would very likely also be able to catch almost anything that has scales and swims.

Nov Inflatable fishing boat input They are typically used for spinning deer hair or for synthetic materials that call for an abnormally strong yet small-diameter thread. GSP thread holds up well to toothy fish and creates durable flies. The slickness can be a liability in other applications however, particularly dubbing retention, and the dye used to color them is not as stable on GSP thread as it is on other materials, so I only use white.
Kevlar was sort of a precursor to GSP. It lies quite flat, is incredibly strong, and comes in just one size denier. It is most often used in larger spun deer-hair patterns like bass bugs. Dye is not stable in this material either, and can run when you apply head cement, so I only use this thread in its natural color of pale yellow.
There's nothing worse than tying a perfect white bass bug, and watching the thread leach dye into it when you add a final drop of head cement. These two specialty threads are basically interchangeable. GSP thread is much slicker, and both can be hard to cut with your tying scissors. I've heard horror stories about the abrasiveness of both these threads eating bobbin tubes, but after almost 40 years of tying I've never seen it.
GSP thread does come in a wider range of sizes, from 30 denier up to Silk was the first thread used to tie flies and is still wonderful stuff. Two twisted strands are used to create this thread and silk can easily be untwisted to flatten or twisted as you see fit.
It has fallen by the wayside for many reasons, mostly because it's not very strong and doesn't hold its true color when wet. It's still useful in historic applications and I use it for soft-hackled patterns as well as ribbing in some cases, but as a general tying thread it has been surpassed.
After all this guidance, it's still useful to buy several different kinds of threads and sizes and see what suits you and your tying best. While a more consistent and understandable and consistent sizing system would be a lovely advancement, it's not likely to happen.
If you're now a true "thread nerd" and want an even deeper understanding of thread sizing, materials, and breaking strength, check out Martin Joergensen's fantastic thread table on the Global Flyfisher website globalflyfisher.

Denier is defined as the weight in grammes of meters of polyester, nylon or rayon threads. There is also now for most threads a correlation between the breaking strain on most threads for examply typically a 70 denier thread will be stronger than a 30 denier thread. So the best we can hope for as fly tyers is a guide to the thread diameter so that we can gauge the size of head that will be created using a thread.
Of course a twisted thread will be thicker than an untwisted thread which will lay flatter on the hook. Most threads are made by twisting multiple plies to make the required size. Left Twist or Z-Twist thread is twisted to the left and works with almost all single-needle machines.
Right Twist or S-Twist thread is twisted to the right and is used with some U. Really interesting information on the wonderful ranges of tying materials for home tying. The detailed explanations of the uses and breaking strains is remarkable.
Just think, only a few decades ago it was only thread, cotton, nylon or silk that was available.
