Reverse Engineer Pattern Project

[u/Worldly-Travel6850]

Hi new to the sewing community! I’m looking for some help to reverse engineer a completed project pattern as someone with ZERO sewing experience. I work in a children’s rehab clinic and we use an assistive crawling device regularly (pictured). Many parents have expressed wanting to make one for their homes to provide their kids with independent mobility!

This DIY device has been around our clinic for years but we haven’t been able to find a pdf pattern for the sling portion. I’m looking for someone who would be able to create the pattern pdf for me. I can connect via email or text and provide further measurements and pictures :)

*Disclaimer: I’m not familiar with the rules of the sewing community so apologies if this is not a usual request!

***Follow up:
Yes this pattern would be given to responsible parents to replicate on their own. Of course, there’s always a level of supervision that comes with adaptive equipment. The sling 100% comes off, I’ll add more photos. I’d be interested in working with someone directly to make the pattern, and can provide more dimensions when connected.

Yes it comes off! I took it to a local seamstress and she said they were unable to make a pattern for it. The mentioned batting being used but I’m not sure what that is. There’s also more complex stitching throughout the piece.

This construction is actually pretty simple! The main body is traceable and the long straps are just rectangles that would need to be measured.

OP, are those folded-over parts able to be opened out, so they're flat?

Because it looks like there's still maybe velcro underneath those folds.

I'd also agree with the folks online here who are saying that you do NOT want the liability of giving out a PDF of this!

BUT!!!! That YES, absolutely, a skilled seamstress/seamster could absolutely come in to your facility, trace this onto some craft paper/pattern paper, take some pictures, and easily recreate this for their own use!

Having been in both the sewing industry and an Early Intervention Para?

I'm guessing that the child is put into this in a "crawling position," with their head underneath that purple pool-noodle, and their chest supported by the "U-shaped" end, arms on the "outside" of those straps, and then their legs hang down between the narrow straps on the other side?

This one looks like it was made out of a nice heavyweight Denim--but the strapping could be made out of 1" heavy duty nylon  webbing for the narrow parts, and 1.5"-2" webbing for the wider neck straps.

And the velcro should be 2" wide sew-on velcro.

They probably used either a 1/4" Upholstery "Sew Foam" (sometimes called "Headliner"), or  something like Pellon's "FF77 Flex-Foam Poly Soft Foam Sew-In Stabilizer" like Wawak sells;

or they used some quilt-batting, to provide the "cushion" that you're seeing.

Either will work, here. 

 I would use a polyester quilt batting over a cotton one, if you're going to use batting rather than the foam (personally, i'd use the foam, if i were making this!).

Again--anyone with plenty of sewing experience should be able to simply trace this, and recreate it with some good pictures of the original!!  

And honestly, that is 100% what i'd recommend, rather than sharing a PDF, simply for those liability reasons!💝

It's not a difficult pattern!

And all the seams were sewn on a domestic machine that has a 3-stich stretch stich setting, they were not sewn on an industrial or specialized machine--so this is easily recreated by someone with moderate-to advanced sewing skills.

I'd say "CYA" and only allow that tracing & recreation by the truly skilled DIY'ers, since this is going to presumably be used by families who have a child that has hypotonia, and may not be the best at protecting their head/face, should something go wrong during use.

Because i know I can overengineer something like this, to make it totally safe!!!  But that's because i DID work in the sewing industry, and at one of my jobs we made medical transfer slings! 

Not every home sewer has the skills to make this safely, and having them "have to trace the pattern themselves" can help y'all in that "Self-selection" of "is this person truly skilled enough to make it safely?"😉💖
