Returning to Ceramics

On Thursdays, I have began to return to ceramics. One of my many favourite art forms because whatever you create it will be different to anybody else's.

I have began to get back into slab work (my first piece of pottery I created was a Day of Dead skull focusing on Light & Day which relied a lot on textures & colour).

I also created two bowls and wanted them to look the same in design but different in size. I gave the items a theme of flowers (mainly poppies & daisies) but see if you can guess what was used to create the imprints?

Sorry it's upside down - but these are the poppy coasters (slab work)
