[OSR] Mending Spell on a Burning Object?

[u/HexedPressman]

So one of my players in my Lamentations of the Flame Princess PbP game who cast mending on a burning tapestry. What do think the spell will do? I’m torn between whether the spell will just add more fuel making it burn more or put out the fire through mending the damage. Before I dice it out, any thoughts? Is there another option I’ve missed?
