Sewing Instructions

Selecting the Optimum Thread

When sewing Swarovski Crystals, particularly Sew-on Articles and Beads, synthetic threads with a thread count of Nm 50–80 are most suitable, due to their abrasion resistance. Monofilament and pure cotton yarns are not recommended due to their limited abrasion resistance.


Selecting the Stitch Type

In general, Swarovski Crystals can be sewn on using a variety of stitch types.

Straight Stitch

A stitch length should be selected that allows the stitches to fall in the spaces between the cups.

Zigzag Stitch

The length and width of the stitch must be adjusted to suit the element being applied. The width of the stitch (B) should be 0.5 mm –1 mm broader on both sides than the crystal element (A) being applied. The length of the stitch (C) should be equal to about 2/3 of the width of the stitch. In some cases the tension of the upper thread must be reduced. 

When applying products using a zigzag stitch, the use of an adapted presser foot is recommended.

Button Sewing Program

Crystal Buttons and Sew-on Articles can be applied using a button sewing program. Here the hole spacing must be selected.  


Application Using a Sewing Machine

The right choice of needle (strength Nm 70–100), sewing thread and thread tension (upper and lower thread) are particularly important for applications with a sewing machine. The fabric must not become gathered and the upper and lower thread should run easily and smoothly. 

Tests should be conducted on the original material before beginning production. 

Before sewing on Crystal Buttons with a machine it is essential to set the sewing machine to the correct hole and stitch length, and stitch width. This prevents the crystal from being damaged during application and reduces the risk of injury. 

When sewing high, multi-row products, there can be problems with the sewing machine feed, caused by a slanting presser foot. To avoid this, position a height compensator beneath the presser foot to ensure it sits parallel to the material, allowing the fabric to feed through properly.
