Review on 🧵 DREAMSTITCH Invisible Zipper Presser Foot with 0083677000#75 Shank for Bernina New Sewing Machine: Enhancing Your Sewing Experience by Kristen Reid

Used to attach invisible zippers. There are two tunnels. You use the left tunnel for one side of the zipper and the right side for the other side. The tunnels should be the same, but the right side is not the same as the left. This resulted in the zipper's teeth being sewn together, rendering the zipper inoperable. After throwing up 4 times, I moved the machine needle to make up for the disappointment. I was expecting the attachment to attach the zipper easily but was very disappointed.
