I'm a little limited in what I can take with me on the train, but I can try to be useful here:
Marketplace / Silver arrow
I'll see what I can do out of wire and card/clay painted silver
Marketplace / Garrotte
This is just thread or wire with handles on the end? I can have a go.
All change / Sword
How good are you hoping this will be? I might have a crappy foam dagger somewhere.
All change / Bone
This feels like something that can be made in paper mache or clay. If nothing else, it's not like I'm using my femur for anything.
The winning quest / Paper machee statue
I can have a go at this but I'm not confident in my paper mache skills. Though maybe that's what we're looking for.
Credit check / Key
Credit check / Pair of glasses
I can provide these but I'll kind of need them back to see/get in my house
Merlot the Magician / Piece of paper
Doodle bug and Family Special / Scroll
Scrolls are just weathered pieces of paper with ribbon tied round them, right? I can try that.
Marketplace / General market crap (bottles, jars, scrolls, etc.)
I have a load of jars saved up but I don't know how suitable they are.
Marketplace / Monkey paw
If nobody else has a monkey paw handy (if they do: why?), I can attempt to make something out of the crap in my crafting cupboard.
Credit check / Post-it note
I have a post-it note addiction.
Marketplace / Small vial of liquid
I probably have some tiny bottles with corks if that'll do.
The winning quest / Other random crap (Toy car, stick of chalk, slinky for instance)
I have so much random crap in my house you have no idea.
Mockery / Pearl necklace
I don't have a pearl necklace. What I do have, however, is a load of pearls and thread/elastic.
I can't guarantee what I make is good enough but it's something?
