How to Stitch the Perfect Stitch Length for Quilting

You can do embroidery or you can do free motion. If you're quilting a quilt sandwich (fabric, batting, backing fabric), you probably want to do free motion quilting. Embroidery would work better on fabric (with a stabilizer) but without the batting and backing fabric.

For free motion, you want a free motion foot--your machine's manufacturer probably provided one in the accessory kit (called a darning foot) or there are many generic free motion feet available for purchase (ie Big Foot quilting foot...). The BIG difference with a darning foot or free motion foot is that the shank is shorter than other presser feet because there needs to extra space between the presser foot and the needle plate so the quilter can easily manipulate the fabric. Usually, free motion quilters will drop the feed dogs to avoid feed dog interference with the fabric's movement, however, some quilters don't drop the feed dogs--just whatever works best for you and your machine. In addition, I use a Supreme Slider on the sewing machine surface--a silicone mat that provides a slick surface to help the fabric move.

There are a lot of web sites and video tutorials on free motion quilting. Take some time to watch them and then practice, practice, practice! It's an acquired skill so the more you practice, the better you will be.

According to the manual, your machine does not have the capability to drop/raise the feed dogs. Instead, there is a cover plate that is installed over the feed dogs when performing darning or free motion quilting.

Check that your stitch length is set high enough to actually move the fabric. Some machines also have a presser foot pressure adjustment that will increase or decrease the amount of pressure the presser foot applies to the fabric and the feed dogs. If your machine has this adjustment, it may help to increase the pressure so the fabric will move better. Another thing to check is whether you are using the correct presser foot that will actually rest on the feed dogs.

Another possibility is that the feed dog points have been worn off. When the points are worn, they no longer grip the fabric like when new. When stitching, be sure to never run the machine with the presser foot setting directly on the feed dogs, it without fabric.

Be sure to have a darning foot or free motion quilting foot (this presser foot is shorter in height so when you lower it, it will not press the fabric to the feed dogs). The foot must allow space under it so the fabric can be manually moved.

The last step is to lower the feed dogs so they are not interfering with your manual manipulation of the fabric.

Lots of web sites about free motion quilting.

You need an embroidery foot, that doesn't lay on the fabric like a normal foot and allows free motion of the fabric. If you are using one, be sure it is the appropriate foot for your machine and that you have pushed the appropriate button or place on your machine so that the machine will place the foot in the correct position.

When stitching together a quilt sandwich, it is recommended to use a walking foot on your machine. The walking foot moves the upper fabric in conjunction with the feed dogs. Sometimes, if the quilt sandwich is not too thick, a roller foot can also help but may not be sufficient for a quilt sandwich.

You may also check the presser foot pressure on your machine. This regulates the amount of pressure the presser foot applies to the fabric and the feed dogs. If the pressure is too strong, it will tend to push the upper layers of fabric, creating a bubble look. If the pressure is too loose, there is not enough pressure for the feed dogs to physically pull entire quilt sandwich under the presser foot.
(The pressure is adjustable depending on the types of fabric and thicknesses being sewn.)

Presser foot tension is to low for the weight/finish of the fabric, or bottom dogs are worn.

• The feed dog feeds the fabric under the presser foot while you guide the fabric.

  
  

• The feed dog regulates the stitch length by how much fabric passes under the presser foot as the machine stitches.

  
  

• It is important for you to not push and pull the fabric under the presser foot. Allow the feed dog to move the fabric, so that you do not bend and break sewing machine needles.

Hope this helps.

Hi, when you quilt straight lines using the walking foot, you need the feed dogs up, to move the fabric in a straight direction under the needle. When you do free motion quilting, which is done with a darning foot, your hands move the fabric in many different directions. Since you want to be the one to move the fabric, you put the feed dogs down and you do the work. So when you use the walking foot, keep your feed dogs up. When you use the darning foot, feed dogs down.
