Here is a pack of high resolution denim textures. There are 21 images around 4500-3000px. I have scanned plain blue, black and beige denim textiles that can be used as backgrounds and also pants front and back pockets; there are also good seam details. I do have more of these jeans textures and there will be a part 2 later on.
You can view in the image below the actual jeans cloth details for the first three textures. The download link is right after. If you find these useful share the post or leave me a comment. Thanks!
