Will the Singer model 384 do quilting and if so, which foot is required?

SOURCE: How do I attach a walking foot

Okay let's get started.

• First let's look at the walking foot.
• Turn the bulky body so that it's away from you.
• On the left you see a groove that is going to be where you attach the foot to your machine.
• On the right is a u-shaped arm which you can move up and down. It will go over the needle clamp

• Loosen the foot screw until it almost comes off. (if it does come off, screw it back on a bit.) The screw is on the left of the foot-bar.
• On the right you'll see the needle bar with a needle clamp (what you tighten when you replace a needle) on the right of the needle-bar.

• slide the walking foot into position so that the foot screw is in the slot on the right and the u-shaped arm is over the needle clamp, with the needle clamp in the middle of the u-shaped opening.
• Tighten the foot screw securely, it's going to be under more strain than normal.
• While you're at it, check that the needle-clamp is nice and tight as well.

I have a new machine. This is the second the first had the same problem so I exchanged it. It worked fine on 1 project on both machines the next the time it did the following. When sewing stich #8 which is a zig-zag stitch with a straight line on one side, I get the #8 stitch on one the bottom side and the #13 stitch on the top side. I have read the manual, also re-wound the bobbin twice re-threaded the machine twice and changed the needle none of these worked. Do you have any suggestions.

You have to unscrew the presser foot, then attach the WF, using the same screw.

Make sure the lever on the WF rests on top of the needle bar clamp.

Some WF have a two prong lever and this fits around the needle clamp like a lobster claw.

You have to unscrew the screw for the presser foot first. The walking foot will then fit. Use the same screw to attach the walking foot. Before you insert the screw, take the white handle on the walking foot and slide it on the screw arm for the needle. Now tighten the screw.

The 7442 does not have feed dogs which can be dropped. You need to use the "Darning Plate" which came with the accessories.
