The edge is pressed into a channel in an aluminium frame.

I'm not an IP attorney, but I'd say you should take that video down until you have a patent in-hand.

Then, sell it to Brother.

It would costs you $10,000 or more to do the research and have a patent filed.

Also, there are different guide plates out there for different tasks.

From my research, the only guides available are for hemming.
Everyone makes them for general work. There's really no patent on cloth folding before stitching. It's kinda public domain, industry common knowledge.
But, for specialty work, most are custom made for each system.
And to get one, you buy the entire system or have something made.
Finding a fabricator that can even understand what you want is a challenge.

This is a specialty item, but for someone who doesn't want to spend $50K on and automated system when they only make a few of these displays a year.

Started the video but had to stop. Kept remembering that sewing scene from Better Call Saul.

I've got another I haven't uploaded yet...

There was a gunsmith in PA that had a knife sharpening fixture to do all sharpening angles and other tools like scissors, etc.

He said he had given up on getting a patent due to the cost and research involved. His profit margin would take years to offset the patent costs.

I would just continue making your jigs until someone tells you to stop.

And even then, I won't.
They're basically industry standard accessories.
