Cobblestones

[heda]

Planning another small project, I'm looking to pave an area around 20” x 9” with cobblestones. I don't want to use Metcalf as I want them embossed.
The best I can find is the Vollmer 46041, at £2 for a sheet 250mm x 125mm there a good price.
Has anybody used them or can you suggest a suitable, reasonable priced alternative.
I want something I can just stick down rather than making my own with clay or whatever.
