Setup
Before beginning any sewing project, ensure your needle is appropriate for the fabric and thread thickness. For machine sewing, properly thread your machine according to its manual, ensuring the thread unwinds smoothly from the spool. For hand sewing, cut the desired length of thread and thread your needle. The waxed coating on this thread helps prevent tangling during the threading process.
Operating
Gutermann Waxed Extra Strong Linen Sewing Thread is designed for durability and strength. Its waxed finish provides smooth passage through fabric and reduces tangling, making it ideal for hand sewing, leatherwork, bookbinding, and other heavy-duty applications. When sewing, maintain consistent tension for even stitches. The extra strength of this linen thread makes it suitable for projects requiring robust seams. For best results, use a needle size that accommodates the thread's thickness without causing excessive friction.
Maintenance
This thread is composed of 100% linen. For care of finished items, the thread is washable at 30 degrees Celsius (86 degrees Fahrenheit). It is recommended to hand wash items sewn with this thread to preserve the integrity of the stitches and the fabric. Avoid harsh chemicals or high heat drying, which may compromise the thread's strength and wax coating.
Troubleshooting
- Thread Tangling or Knotting: If the thread tangles or knots during use, check for proper tension settings on your sewing machine or ensure your hand sewing technique is consistent.
- Thread Fraying: If the thread appears to fray, inspect your needle for burrs or ensure it is the correct size for the thread. The waxed coating helps prevent fraying, but excessive friction can still cause wear.
- Thread Breaking: If the thread breaks, consider if the tension is too high or if the needle is too small for the thread's thickness. Ensure the thread is not snagging on any part of your machine or work surface.
