Husqvarna invisible zipper foot

Instructions

• Mark the length of the opening on the seam allowance and on the zipper itself. The excess length should remain at the bottom of the zipper. 
• Attach the invisible zipper foot. Select straight stitch with center needle position. Length 2.5–3.0.
•  Open the zipper.
• Place the right half of the zipper on the two fabric pieces, with right sides together. The zipper should lie directly on the seam, with the top stop 2 cm below the raw edge of the fabric.
• Press the zipper with your finger and lower the presser foot, making sure that both halves are inserted into the right groove under the foot.
• Adjust the needle position so that it lines up with the guide on the front of the presser foot. Backstitch and sew. Stop at the mark on the zipper and the seam allowance, then backstitch to secure the seam.
• Place the left half of the zipper right sides together on the left side of the garment. Lower the presser foot with the left groove over the zipper teeth. Make sure the needle is perfectly aligned with the guide on the front of the foot. Repeat the same steps for the second side.
• Pull the slider to close the zipper. Place the fabric and zipper right sides together. Attach the standard zipper foot to the left of the needle. Adjust the needle position to the right. Start at the bartack and sew under the zipper. If the zipper is too long, sew an overcast bar between the teeth 3 cm below the part inserted into the fabric. Trim off the excess zipper below the overcast seam.
