I bought some of my leather stuff at Packer leather in Narangba (the Klassic Craft I think it was in brandy https://packerdirect.com.au/product/klassical-kraft/) and some of the items from eBay.
I borrowed a very good book from the library called "Pigpong - Tanned Leather Hand-Made Bags", it was very thorough and helpful, lots of pictures. I can really recommend it for beginners. It includes patterns (with size instructions for printing) and a list of products needed. Unfortunately some of the items are US based and I cannot find them here. Bought some glue off eBay. Instructions were in Chinese .... LOL - that led to a couple of trial-and-error situations, but at least I was not glued to the item.
I took pictures and measurements of all the items that my son wanted included before he went overseas, and am currently making them out of cardboard and tape. My plan is to lay them out and see how it works. He has shortened his list of knives - has had a couple of them stolen and one broke, so I will have to do a recount.
Figuring I will make the outside of the case in cowhide and the inside in kangaroo, to make it more sturdy, but not too bulky. I know kangaroo hide is very sturdy, but I just feel like the roll will end up being a banana instead if made only from kangaroo. I will start a new thread when I get started more seriously. I totally understand the critique I got for not replying fast, and understand the frustration of the people who are helpful. Hard thought when many days I just do not function /shrug.
The post Tugadude linked : https://www.instructables.com/Leather-Chefs-Knife-Roll/ is awesome. I am however figuring on a double stitch with a small space in between the knife pouches. I am not keen on the rivet look, but I can see the sense of the seem and the top and bottom rivet that you have on your roll.
