How to Use a Rolled Hem Presser Foot 

Using a rolled hem presser foot can give your sewing projects a neat and professional finish. Here's a step-by-step guide:

• Turn off the machine: Before making any changes to the presser foot, always turn off your sewing machine and unplug it if possible. This is a safety precaution.
• Remove the current presser foot: Loosen the screw that holds the presser foot in place and carefully remove the standard presser foot. Set it aside in a safe place.

• Identify the correct foot: Make sure you have the correct rolled hem presser foot for your sewing machine model. Some machines may require specific types of presser feet.
• Attach the foot: Align the shank of the rolled hem presser foot with the presser foot holder on your sewing machine. Slide it into place and tighten the screw to secure the foot.

• Stitch length: Set the stitch length to a short setting. Typically, a stitch length of around 1.5 to 2 millimeters is suitable for a rolled hem. This short stitch helps to create a tight and neat rolled edge.
• Thread tension: Check and adjust the thread tension if necessary. For a rolled hem, you may need to slightly reduce the tension to prevent the fabric from puckering. Test the tension on a scrap piece of fabric before starting on your actual project.

• Cut the fabric edge: Trim the edge of the fabric to be hemmed to a straight and even line. A width of about 1/4 to 1/2 inch is a good starting point for the fabric to be rolled.
• Press the fabric: Use an iron to press the fabric along the edge to be hemmed. This will make it easier to feed the fabric through the presser foot and create a neater hem.

• Position the fabric: Place the fabric under the presser foot with the edge to be hemmed aligned along the left side of the foot. Some rolled hem presser feet have a guide or groove that the fabric should follow.
• Start sewing: Slowly lower the presser foot and start sewing. As you sew, the presser foot will automatically roll the fabric edge under and stitch it in place.
  
• 
  
• Guide the fabric: Use your hands to gently guide the fabric through the presser foot. Keep the fabric moving smoothly and evenly to ensure a consistent rolled hem.
• Handle corners and curves: When sewing around corners or curves, slow down and pivot the fabric as needed. You may need to adjust the position of the fabric slightly to maintain the rolled hem.

• Backstitch: At the end of the hem, backstitch a few stitches to secure the thread. This will prevent the hem from unraveling.
• Trim the threads: Use a pair of scissors or a thread cutter to trim the excess threads. Be careful not to cut the fabric or the stitches.
