Would those of you with DIY mattress cases please post pics

Hi, I am requesting pictures of your DIY mattress cases. Specifically we would like to see pics of the zipper, where it begins & ends, & if you have an APM cover, please show how it is connected where there is no zipper. the inside top part & the underside where it is sewn without the zipper. I would like to see how the seams are done.
Thanks in advance, I know it is a lot to ask, so maybe wait until you are changing the sheets. If you are one of the experts, I’ve looked on all of the sites & none of the pics shows good closeups of what I am trying to see, and most of all of the pics do not enlarge well.
I’m trying HARD to do my own research before buying, I’ve looked through ‘archives’ here extensively, & have been all over reddit trying to find answers.
Since these mattress cases are not returnable, I’d like to see enlargable closeups before purchasing. Thanks Much!

Sorry, maybe I wasn’t clear, I am looking for pics of mattress cases that were purchased for DIY beds, like the cases that APM has-really would like to see the zipper & also how the permanently attached non zippered part is sewn. Would like to see good pics of the cotton cover more than the bamboo.
NOT looking to make a DIY case

I thought you wanted to see how a zipper is sewn securely into the cover which this DYI presents and the section beyond the end of the zipper where the mattress is sewn together.

The fact that that site is presenting a DIY is not the issue, it is to show how the zipper is securely attached, and the cover is sewn together beyond that point.

If you specifically want to see a pic of an APM cover at the point where the zipper is sewn in, or the point beyond where the zipper is sewn in, simply call them and ask them to send you a picture.

The DIY should show how that is done too.

I thought I’d ask on the forum from others who already own it, & the pics would be here, for reference, for anyone else who may have that same question in the future.

Ah, got it. I am sure APM or one of the companies would post those type of pics if you call them and ask.
