I'm looking for a darning foot to use on my Quantum CXL so I can do free motion quilting. Is there one available?

i don't know of any machines that can't free motion quilt. you will need to either drop the feed dogs or buy an attachment to cover them, then buy a quilting foot that fits your machine .

You need a darning foot or free motion foot. Other than that, there are a lot of videos and web sites available. Just search for "free motion quilting." The only other thing is practice, practice, practice, It takes time and practice to do it well.

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.

Free motion is similar on most machines.

Install a brand new sharp needle (embroidery, top stitch, microtex, or universal) of the size that is compatible with the thread weight and fabric.

Drop the feed dogs. If you machine doesn't have the capability, there should be a feed dog cover in your accessory kit that needs to be covered,. This prevents the feed dogs from interfering with your manual maneuvering of the fabric.

Install a darning foot or free motion foot.

Test your stitch and adjust the tension so the threads meet in the middle of the fabric.

Then, it is a matter of practice, practice, practice...

Although the dealer may no longer sell the "original" foot for your machine, there are usually "used" presser feet available from sites like eBay. OR, you can purchase non-Pfaff presser feet that will work just as well on your machine. Just be sure to verify that the presser foot is compatible with your model (the shank style will determine whether it will work on your machine).

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.

#26 is an embroidery foot. Why are you using an embroidery foot for free motion quilting? A #24 free motion embroidery foot will work but not the #26. Try using a darning foot that is just a smidgen shorter so there is space between it and the needleplate for you to freely move the fabric. (Adding a Supreme Slider sheet to the work surface of your machine helps make the fabric glide much smoother.) A standard presser foot is made to press the fabric against the feed dogs so the feed dogs will move the fabric. When free motion quilting, you would drop the feed dogs and move the material with your hands.

Depends which model Bernina you have (new or old style presser feet), which will work on your machine. There are also many generic darning/FMQ feet available that will work on your machine.
