When selecting the right eyelet for textiles, leather, or craft projects, not only the inner diameter matters – the outer shape and surface texture also make a difference. Those who want to process products professionally often face the choice between T1 eyelets and T3 eyelets.
But how do the two variants differ visually and functionally?
An overview of the difference between T1 and T3 eyelets:
-
T1 Eyelets: The classic variant with a rounded oval shape. The head is slightly curved (concave), which gives the end product a traditional, tactile structure and a timeless look.
-
T3 Eyelets: This version has a modern, smooth surface that lies particularly flat and looks extremely elegant. It conforms perfectly to the material and ensures a very clean, mechatronic finish.
When to choose which eyelet type?
-
Applications for T1 (Classic & Curved): Ideal for more rustic clothing, leather goods, heavy cotton fabrics, or handicrafts where the eyelet should stand out plastically.
-
Applications for T3 (Flat & Modern): Perfect for modern fashion collections, flat-lying cord channels on hoodies, sportswear, or elegant accessories where nothing should be bulky.
Professional tip for processing:
Since T1 and T3 eyelets have different head profile shapes (curved vs. flat), you will need the exactly matching pressing tool in your eyelet press:
-
A T1 tool has a curved upper form so as not to crush the curve of the T1 eyelet.
-
A T3 tool is flatly shaped to evenly press the flat surface of the T3 eyelet.
