Thread Spools
By Steven H. McGarthwaite

Every fly tier begins to have preferences shortly after they start in fly-tying; I am no different than any other fly tier. I have preferences for the brand of fly vise, tools, and hooks I use. I do not have a preference for choice of thread brand (Uni, Danville, and ect.) or thread type (nylon, polyester, silk, ect.). I do have a preference for the thread spools I use in my fly tying. Some people avoid a certain brands of threads because of the spool the thread is sold on. Again, I am not any different than other fly tiers, I may use a company's thread, but I do not use their spools. How can simple spools make a difference in how you tie flies?

Thread spools are not just for storage of the thread, they are also a component of your bobbin, when tying a fly the two parts have to work together as a team. Different brands of thread have their own unique spool design; some designs are better than others. Here is a list of the different spools by the brand names of the threads.

Danville spools are slit deep into the hub of the spool with a diagonal cut. I find the thread tags hard to reattach onto the spool because the tension of the remaining thread prevents the rim slit from opening easily. The thread can easily snag on the slit when using the spool on the bobbin. For some reason the Danville brand insists on placing the label on the slit end of the spool.

Uni spools have a diagonal notched slit on the rim, but it does not cut into the hub of the spool. Uni has the spools label on the opposite end of the spool, the end with the slit for the thread tag. This is an improvement over the Danville design. The thread can catch on the slit in the rim when used on the bobbin.

Pearsall sells it silk thread and floss on miniature spools, you need a smaller bobbin to use the thread. The spools have a slit on the outside edge of the spool, this is better than the Danville or Uni slits, but this also can snag the thread when used on the bobbin.

Waspi has a spool that does not slit the rim to hold thread tags, instead they have a plastic washer attached to one end to secure the thread. There is nothing on the spool rim to snag the thread.

Gudebrod has a similar design as used by Waspi; Gudebrod has an expanding cap on both rims for securing the thread tag. There is nothing on the Gudebrod spool rim to snag the thread when used with the bobbin.

Most brands of thread sell their thread wrapped right up to the lip of the spool rim. I have noticed that many times my thread has broken because the thread rolled over the rim and wrapped around the wire foot holding the spool on the bobbin. I have, for many years, been transferring half of the thread on a new spool to a different spool, to avoid the thread jumping over the rim.

I use Waspi and Gudebrod spools exclusively with my bobbins. I transfer the thread to empty bobbins by using the thread transfer device on my sewing machine. You also can transfer the thread by using your bobbin to hold the new spool of thread and wind the thread onto the blank spool.

Some may think I am exaggerating a small thing, such as the thread spools. Small annoyances become big annoyances when they happen too often. I do not like annoyances when tying flies, especially things that I can correct. ~ Parnelli
