Aha, that makes sense. That's probably what you meant by weaving.
You weren't talking about "superimposing", but about "N-upping".
It's important to use the correct terminology.

Why PdfStamper???
Create a Document
use PdfWriter as the writer object
open the document
for each page you want to add {
use PdfReader to read the page,
set the page size with document.setPageSize();
trigger a newPage() with document.newPage();
add the PdfImportedPage using addTemplate();
}
close the document
If you need to add two pages on one, take a look at the NUp example from
chapter 6.2.3
(A hurdle you may need to take, is that it may be difficult to set the
page size of the first page if you're using an old iText version.)

The book has several examples where PdfCopy, PdfSmartCopy and PdfStamper
are used in a chain.
For instance: small documents are created in memory with PdfStamper
(using a ByteArrayOutputStream),
and then concatenated using PdfSmartCopy (writing to a FileOutputStream).
