Thread Comparison

As a tatter we use a lot of different threads. A single strand of thread can be easily pulled apart. Two strands are a little bit harder to break, but when you start twisting strands together they become much stronger. If you take embroidery thread you can see that it's made up of 6 strands of thread, but if you look closer, each of those strands is made up of 2 loosely twisted strands. If you look at perle cotton the strands of thread are much thicker, but there are only 2 strands not six and the strands are more tightly twisted.

A 3 strand thread can have finer individual strands than a perle cotton, but the strands are twisted much more tightly together.

You may have heard of people talking about 'S' twist and 'Z' twist. The letter S starts on the top right and moves to the left. The letter Z starts at the top left and moves to the right. In the same way strands of thread can be twisted together by twisting them from the right to the left or from the left to the right. Flora and Olympus are 6 cord threads which have strands of thread twisted in both directions. First pairs of strands are twisted together in one direction, then 3 pairs are tightly twisted together in the opposite direction. A 6 cord thread is strong and durable. It will take tatting and retro tatting without becoming worn or fuzzy.

Most tatting threads are cotton. You can use other fibres, but the majority of the time you use cotton. Cotton is soft, fluffy and fuzzy and when it's spun together it's still fuzzy. Threads with lots of fuzzy bits in it doesn't tat very well. John Mercer a 19th century chemist devised a method of chemically treating cotton fibres to remove the fuzzy bits and it also gives the thread a nice shine. The process is called Mercerization and even today we see the word mercerized on most of the threads we use for tatting. Fuzzy bits don't slide very well so most of the threads that are really good for tatting are mercerized. Polishing the thread gives it extra lustre and makes the knots slide easily.

Sometimes I want a really fine thread to create something delicate like an edging to float on the edge of a wedding hanky. Other times I want a nice thick thread to make a quick project. Whatever I'm making, I sometimes find that while I have the right colours in my stash, they're not all from the same manufacturer or they're not all marked with the same size.

Take a look at the picture on the left. All of these flowers were tatted using the same pattern and there are 7 different brands of thread that all look remarkably close in size. There is a measuring tape down both sides one in metric and the other in inches so you can judge for yourself.

The first thread is Flora size 20 and it's a 6 cord thread that's nice and crisp the stitches slide easily and the thread doesn't fall apart if you have to undo and redo sections of your tatting. It isn't as well polished as some 6 cord threads so it has more of a matte finish. This is marginally the largest of the samples.

The second thread is Opera size 20. It's a 3 strand thread that's more polished than the Flora so it's shinier and it's softer to the touch. It will take some gentle retro tatting without too much effect, but if you have to re-work the same piece several times the thread gets fuzzy and starts to fray.

The third thread is Oren Bayan size 50 which is a 3 strand thread and shiny like the Opera thread but it seems to be a little more tightly twisted and a little crisper and stronger so that it has less of a tendency to fray.

The fourth thread is Altin Basak size 50 another 3 strand thread. It may not be apparent from the picture, but this sample is the smallest of the 7 flowers. The thread is tightly twisted and well polished, but not as shiny as the Opera or the Oren Bayan. Again, as it seems with all of the 3 strand threads, they don't handle re-tatting very well.

The fifth sample is Olympus size 40. In my opinion it is the best thread of any of these shown to work with. It's a crisp 6 cord thread with a nice polish. If you tat tightly with a 6 cord thread, the project will hold it's shape without much need for blocking. The thread has a nice sheen to it and it will take multiple attempts at tatting and un-tatting without any apparent affect on the thread.

The sixth thread is DMC Perle (or Pearl) 8 which is a 2 strand thread. The thread is soft and lustrous, and the stitches slide easily but the thread won't take well to multiple attempts to tat and un-tat. It can separate and fray easily if you grab only one of the strands doing a join, but if you work carefully the sheen makes for a lovely finished product.

The seventh sample is 3 strands of embroidery floss. This is a no-name thread and didn't make a very satisfactory flower. DMC or Anchor embroidery floss have a nice sheen that makes the stitches slide easily. However, this sample makes the point; 3 strands of embroidery floss makes a finished project roughly the same size as all these others.

I haven't done Cebelia or Manuela size 20, but I will and you will see that they too are almost the same size. So there you have it. 7 different threads with sizes marked on them from 8 to 50 and yet the finished size of the tatting is almost the same. So the next time you need a colour and you don't have it in the selected brand, you'll know what you can substitute, and if a pattern calls for a brand you don't have, instead of giving up until you can get to the store, select and alternate brand, and get to tatting.

Excellent article on threads Sharon! Thanks for researching and sharing!

Thank you so much for this information. I am a new tatter and I have a good amount of Lizbeth thread. I was a little disappointed that you didn't even mention this brand. Ahhh, cry, cry! What is your opinion of Lizabeth brand for tatting, compaired to the other brands that you talked about? I'm just curious if you've tried it. Thanks again.

Lizbeth thread is a relatively new brand and wasn't readily available at the time this comparison was done. It's a really good 6 cord thread, strong, smooth and in a remarkable range of colours. It's very similar to the Flora size 20 thread.

Linda said...

Wow, you're awesome! Thank you for the fast response. Even though I just started tatting, I have found Lisbeth to be much better than some of the other threads that I have tried. I value your opinion as an expert tatter. Thank you again.

Lizbeth is fast becoming the thread of choice for tatters. I have only used the size 20 thread, but I understand that the other sizes are equally good. A few people have found the thread to have inconsistent thickness, but overwhelmingly, the response to the thread has been positive. Barb Foster from Handy Hands is the producer of the Lizbeth threads and she is a tatter who understands what tatters look for. Many of the companies producing the vintage threads stopped producing suitable tatting threads, so she stepped in and began the production of the Lizbeth threads with a lot of feedback from tatters. So now there is at least one source for proper tatting thread in a wide variety of colours. Lizbeth is one of the few variegated threads with the short colour changes necessary for tatting. Tatting uses so little thread that using most crochet threads means that small projects end up being all one colour instead of having nice gradual colour changes.
