Thread database
The Thread Database
The Thread Database provides a universally applicable and comparable overview of all textile threads for bobbin lace-making, embroidery, sewing and many other uses. The multitude of different labelling systems for yarn thicknesses on the market simply calls for a clear, comparable solution.
I have been offering this solution since 2013 with my specially developed measurement method, which focuses on the actual diameters of the threads.

You can easily and directly compare different yarns and brands!
I have provided some examples below.
The measurement results are regularly updated and are available to you at any time. Furthermore, numerous links have been provided so that you can place an order directly with the yarn manufacturer if required!
Structure of the database
The yarns in the yarn database are divided into two categories:
  • Manufacturer: You will find all yarns listed in alphabetical order by manufacturer.
  • Thread thickness: Here, all measured threads are sorted by thickness, allowing you to easily find alternative threads that are all the same thickness.
Note: If you are looking for a specific thread, press Ctrl+F and enter the name of the thread.

History
The Thread Database was created as a clear and user-friendly summary of the measurement results from my original thesis at the Kantcentrum in Bruges, entitled in Dutch:

Draad en Patroon; een Zamenspel

Details on this and other numbering systems can be found in the German translation:

Why this order according to my measurement method?
This dD labelling system (average thread diameter in 10 micrometres) offers numerous advantages. In particular, it enables lace makers to find the appropriate thread thicknesses for their lace patterns.
Examples: dD 100 = 1 mm, dD 10 = 0,1 mm).

For example, a thread has dD 15 – a thread that is twice as thick then has dD 30

In classic bobbin lace techniques (Flemish lace, Valenciennes, point de Paris, Torchon), there is a direct relationship between thread thickness and the pattern. Here, it is essential to convert the thread thickness to the pin spacing in the pattern without error.
If the pin spacing is to be 10% greater than the original, we need a 10% thicker yarn. The dD values offer this unique advantage! No other numbering system offers this simple conversion. If the dD value increases by 10%, the yarn is actually 10% thicker. The measurement method is not limited to the raw material, but can be applied to all raw materials. It can be used for all threads with a round cross-section. Fluffy threads can be laid much wider; therefore, only the minimum dD value is given here. Examples can be found on the homepage.

If you would like conversions for your bobbin lace patterns and yarn thicknesses, please use my free dD calculator on my website: https://wolter-kampmann.de/dd-rechner/
A Brief Guide to Threads
The basic materials of the threads are indicated by the standard international quality marks. The designations -S and -Z refer to the twist and plaiting directions of the threads, respectively.

S-twist Z-twist Example:
The illustration shows a 2-step twist 2S-3Z
aus DIN 60900 Stage 1: Two threads are twisted in S-direction,
Stage 2: Three threads from Stage 1 are twisted in Z-direction
