If I told you I made my own slings would you think I was crazy? I use the same webbing, super strong UV treated thread and a industrial quality upholstery sewing mechine and a seatbelt style stiching with three inch overlap. I think it is just as strong plus I can make them in any length I want and are a fraction of the price. what do you all think? would there be a safe way to test it compared to that of normal slings? what are your thoughts?

Definitly get a few of them pull tested before trying them. I don't know enough about sewing to tell you your doing it right.
Allways feels good when you save money and remain safe.

cheapest quickest way would be to take a factory sling, steel biner it to your sling, then pull it between a bomber tree and a truck....if your slings break first....keep working on the stitching pattern.
$4 for a stitched nylon sling isn't bad, considering the quality control they have, and the fact that the bartack is a lot less cumbersome than yours.

And, we of the internet have no basis on which to offer an opinion. Your stitching and consistency might be such that it's fine. Or, you might be using a batch of thread that has weaker spots - we can't tell.
Pull test a bunch - not just one.
And note what Jimdavis has said.

The strongest way would be to tie the sling.

i disagree with coastal climber. Depending on the kind of knot used, tying slings weakens their overall strength considerbably. Stitching is always the best, but take bill413's advice seriously. I like the tree/truck test, you can also do some drop tests and some basic equations to calculate it's strength. Just google fall factors or kn and you should get something worth noting.
I'll stick with my presewn spectra though.

I think a good idea would be to tie a normal water knot with 4-5 inches of tail, then sew the tail to the loop. Although it's not as low profile of knotting as sewing, I think you could definitely rely on it's strength.
