For pinholes on the corners I recommend 2-3" wide peel and stick bookbinders tape from Gaylords. You can use either the cloth type (Filmoplast) or plastic coated cloth. Use the wider size for large cameras.

Now just cut a piece of the 2-3" wide tape of the required length and carefully apply it to each of the four corners, from front to back and lightly crease the bellows at the folds following the original pattern. Repeat for all four sides, then rack the bellows back a bit and contnue to crease the folds following the original pattern.
Bookbinders tape is much superior to Gaffers for this type of repair, IMO. It is both more flexible and thinner than Gaffers, and if proprely applied will not interfere with folding the bellows and/or closing the camera. I recently gave this treatment to my old 5X7 Nagaoka that had developed a few light leaks at the corners, using 2" wide tape, and the bellows is now as good as new. And the repair was real easy and fast to do, and of course cost a lot less than a new bellows. And, unlike some of the bellows patch methods this is a very long-lasting fix.
I am attaching a .jpeg image of the completed repair. For some reason the photograph accentuates the difference in tone between the tape and the original bellows. In reality it is barely noticeable even on close inspection. And the camera still folds up to its wonderfully compact width of 2.25" just as easily as it did before the tape was applied.
