Where could I get large Christmas stencils or similar?

[Elf]

I have an idea in my head about getting the dcs to paint, decorate in various ways, large (30cm+ tall) paper Father Christmases, angels, fir trees etc to stick around the house and look great.

My drawing is not good and I'm a bit stuck as to what I can cut out, stencil, 'copy' etc. There nothing in our local craft shop or WHSmith. Any ideas? Thank you.

Anyone, please?

there are these yellow moon but are small

Thanks Popmum, I had a look and they look okay but yes a bit small. Maybe I should have posted on arts and crafts.
