More precisely, the verb is 折る (oru) and 折り (ori) is the continuative/noun form, 連用形 (ren’youkei), so it’s “folding paper”.

The parent comment pas paper as 'kami', yet the 'k' morphs into a 'g' in the final word. Is this common in Japanese? I've not seen it much outside of Welsh, my own mother tongue.

Interesting. Yes, it's common. If you're interested you can read about it on wikipedia[0] and a bit more in depth here[1].
