Correct upper threading is essential for the Brother LS-2125i’s operation. Begin by raising the presser foot and the needle to its highest position. Place the spool of thread on the spool pin. Guide the thread through the first thread guide‚ then down and around the tension discs.
Continue threading through the take-up lever and then down to the needle; Finally‚ thread the needle from front to back. Refer to the manual’s diagrams for a clear visual guide to ensure proper threading.

Master fundamental stitches like straight‚ zigzag‚ and backstitching with your LS-2125i. Practice these techniques for consistent results and project success.
The straight stitch is the most commonly used stitch‚ ideal for seams and general sewing tasks. Select the straight stitch setting on your Brother LS-2125i dial. Adjust the stitch length according to your fabric; shorter lengths for delicate fabrics and longer for heavier materials.
Ensure your fabric is placed correctly under the presser foot‚ aligning the edge with the desired seam allowance guide. Gently guide the fabric‚ allowing the machine to feed it evenly. Maintain a consistent speed for a neat‚ uniform stitch. Practice on scrap fabric to refine your technique before starting your project.
The zigzag stitch offers versatility‚ preventing fabric fraying and allowing for stretchable seams. Select the zigzag stitch on the Brother LS-2125i stitch dial. Adjust both the stitch length and width; wider stitches create more flexible seams‚ while narrower ones are suitable for reinforcing edges.
This stitch is excellent for finishing raw edges‚ sewing knit fabrics‚ and creating decorative effects. Practice adjusting the width and length on scrap fabric to understand its capabilities. Guide the fabric smoothly‚ ensuring consistent stitch formation for professional results.
Backstitching secures seams‚ preventing unraveling. Utilize the reverse stitch lever on your Brother LS-2125i. After sewing a few stitches forward‚ engage the lever to stitch backwards over the same area‚ typically 2-3 stitches. Release the lever to resume forward stitching.
