From the marvelous publication , which purports to be for the elderly but whose demo is actually the merely cranky of any age:
An old seaman named Tom Carr, who sailed from about every fishing port in England, Scotland, and Ireland, once sent me the word riv, a verb which means to sew roughly. He first heard it in the fishing port of Killybegs in Donegal many years ago; it was used only be the ancients, survivors of the days of sail. From Old Nors rifa, to tack together.

Now, not being an etymologist of any stripe myself (one thing working on dictionaries teaches you is to be highly suspicious of every etymology), I can't say anything about what the Old Norse did or didn't say, but I love this verb and would like to suggest a revival. Rivving is what you do when you sew up something quickly and sloppily–a garment you need for something but don't intend to wear often, a fast alteration not intended to hold forever, a mend that's only barely better than the flaw it's fixing. "Oh this? I just rivved it up. I should really take it apart again and do it right …"
Why should crusty old sailors have all the fun? They won't mind if we borrow this word …
