With differential feed

However, if you move it up, the front will go faster than the back feed dog, causing the material to gather. But moving it down will make the front move slower than the back causing the fabric to stretch. It’s especially vital if you’re using material that puckers.

The most sewing speed it can provide is 1,300 stitches per minute. With that speed, you can finish all your projects in one day. Despite the speed, the quality of your project will remain professional and great looking.
