..oops, forgot to mention, put a pencil eraser - cut off of a pencil - or whatever, on top of that tack point so fabric stays down

My Viking extension table from the 80's has pin holes drilled into it for this very purpose. I've used it a fair amount. A couple of things remember, the pin must be placed in line with the needle. Keeping it in line vital to getting concentric circles. The other thing is that you need to stabilize your fabric. I used this technique to make dozens of those circle travel jewelry bags. No marking! Just cut a square & stick your pin in.
Lots of free patterns for this. Here's one:

it is a really fun technique!
Some of the sew steady extension tables are also pre drilled:

A little piece off a pool noodle will also work in place of a pencil eraser to keep the fabric on the tack.

Great video...I love the ideas you learn from this board.

I have tried this with and without walking foot but my project always looks a little rippled. Anyone have suggestions to keep this from happening?

I had a White machine that was new in 1966 that came with a circle attachment. I remember trying it out, but didn't have a use for it at the time. It seems to me that it was nothing more than a little pin that attached point up in various holes on the machine bed, and had a cap of some sort to keep the fabric from popping off. I wish I'd kept that old machine, but when I inherited my mom's slightly newer Elna in 1986, I had the crazy idea that I only needed one sewing machine.

The beauty of this phone book method is that you can make bigger circles than you could with a device that's attached to the machine bed. I believe I would use some duct tape to attach the phone books either to the machine or the table to make sure my circle didn't turn into an ellipse. Just the vibration from the machine could possibly cause it to slide.

You can buy circle attachments that apparently fit various machines. Here's a youtube video demonstrating a couple of different ones. https://www.youtube.com/watch?v=4WO7nwIKdnI

Cool idea but I too have the circle attachment which works the same way.

Boy, do I agree with this! Love this board.

Slow down stitching speed and use the pivot function if you have one. Stop stitching with the needle down and turn the fabric frequently. Practice before stitching the actual project. You will get the feel while doing the practice session.

I have found a lite weight stabilizer or tissue paper will prevent the rippling, I use basting spray to keep it together....
