Need help learning this construction method please? Interlocking?

Good evening.....

 

I remember seeing something similar to this quite a while back on here....and I thought I saw a tutorial on it, but for the life of me I cannot remember what the construction method is called or how to research how to do it.  I know someone on here can help ,e...everyone is so knowledgeable here.  :)

 

Thank you kindly for your help...I’d like to incorporate this construction method on a bag I’m making soon.

From memory I think it is referred to normally as stitchless construction. I had a play with it awhile back and called it the holy poke method

At any rate here's a couple of pictures that might just help a bit. I do not recommend doing the bottom as I did as it makes it very difficult to weave together without stitching inside along the bottom to hold it together.

 have fun and remember to post some pics when you got it beat.

I finally remembered where I recently saw this! The Sept/Oct issue of "Leather Crafters and Saddles Journal" has a small tutorial on how to make this. They call it a "welted" seam. They mention it was originally referred to as a Marshall welt.

 You can order individual issues but I don't think they have an online option. https://leathercraftersjournal.com/product/2019-volume-29-no-5-sep-oct/

Nice video.  Where can we buy the creaser he is using?  Anyone know?

[Hardrada]

That looks like an electric creaser. Since he's Korean, he probably gets access to stuff we don't, but here's a selection of the same thing available in North America: Electric creasers and other machines.

Thanks so much, everyone!  I really appreciate your sharing this info with me!  I will certainly share pics of the bag once it's finished.  I am going to make it sized to carry an iPad Pro 11", so probably will be slightly bigger than the one in the pic.  I can't wait to start on it.  I bought some 2mm thick foam to try to model a pattern with so that should help in getting the gusset width and stitch distance correct.

Thank you again folks!

No, thank YOU for mentioning that. I've been struggling to find a material thicker than paper and firmer than fabric to make prototype patterns. Now I know what to use.

Hi again folks!

I've been trying to work out this pattern for a while now in between orders and still having a bit of trouble.

In the meantime, I bought a pattern by “hahns atelier” which uses this same construction method for the sides of a long wallet.  I enlarged the pattern to 120% to scale up just that portion of the pattern to use on the pattern for this bag (pic in the first post).

Unfortunately, when you do that, it leaves a large, gaping hole at the bottom of the seam where it needs to be solid to hold small items inside the bag.

I’m going to try to keep experimenting with it, but it’s pretty hard to get everything tweaked right so it will work out to the right size with the proper width to the bag......I’m trying to build in some width to the bag so it’ll hold more than just really flat items, but it’s difficult to do using this stitchless construction method.  

Any brainstorming would be very much appreciated.....struggling here....lol
