Where can I buy small (c20cm) placemats?

[bestpossibletaste]

There seems to be an unwritten rule that placemats need to be 30cm+ wide, but I always think they look too big. I have one set that is 21 x 21cm so fit neatly under the plates without dominating, but they're ancient, shabby, and no longer the colour I want. I've tried M&S, John Lewis, Next, LaRedoute, with no luck. I'm now wading through Wayfair, but without a size filter it will take a while. If you have small place mats, where did you get them?

Jenny Duff (jennyduff.co.uk) does some lovely 22 cm placements, either 22 cm square or 22 cm round. I have the round ones, which completely disappear under my plates. Unfortunately they are expensive, but the melamine and cork is very durable.

Maybe try a place like Etsy or Notonthehighstreet and when you find something you like, ask the seller to make it smaller? I've had a lot of luck with sellers on those sites being willing to tweak details - it often means having to wait a little longer but if the tweak doesn't change the amount of materials or time needed it's often done for the same price.

I have vintage ones for the same reason.

Do you want round or square or rectangle?
Any preference on material? You can get lots on Etsy made out of wood/slate/granite/silicone etc.

I prefer rectangular if possible, and a silver or grey colour. But round may be ok. The size is the most important thing.
