| Overlock or Serger Stitch | Ideal for finishing edges, preventing fraying, and creating professional, durable seams. |
Thread Selection
The thread you choose plays a vital role in the overall durability and appearance of the garment.
| Thread Type | Details |
|---|---|
| All-Purpose Polyester | Strong and elastic, making it suitable for knit fabrics like merino wool. |
| Fine Cotton Threads | Work well with lightweight merino wool while providing a natural finish. |
| Avoid Thick Threads | Thick threads may not fit the needle size and can break during sewing, causing uneven stitches. |
Machine Compatibility
Ensuring your sewing machine is compatible with the chosen needle and thread is essential for smooth operation and a polished result.
| Compatibility Factor | Details |
|---|---|
| Needle System | Refer to the machine’s manual to check compatibility with needle systems (e.g., 130/705H, 15×1, HAX1). |
| Specialized Machines | A serger or overlock machine is highly recommended for handling knit fabrics and reinforcing seams. |
Additional Tips for Sewing Merino Wool
- Pre-Wash the Fabric
- Wash merino wool jersey on a delicate cycle with cold water before sewing. This pre-treatment prevents shrinkage and makes the fabric easier to handle.
