I haven't ever reproduced a pattern exactly, but I have made 2 bargellos and 2 stack-n-whack quilts, but they were all quite different from each other. (Different sizes of pieces, etc.)
Oh, I guess I did make a pair of matching quilts with the same pattern, for my cousin's two boys. Simple four patches. But those quilts were small so I sort of count them in my head as just one quilt, LOL.
