Hi Hels,
I bought mine with a Dutch (I think) lady at Malvern last year (and she was there again a couple of weeks ago ) but I seem to be having trouble to answer your question. But - I have just found this and it seems there are two UK shops that stock them - but you may need to contact them as not on their websites ( so the message says ) here is the link to that message.

I have looked up both shops that are mentioned and they don't list them - but here are their details.
Patchwork Cabin in Gt Bookham Surrey 01372 459908.
Patchwork Corner in Hemel Hempstead 01442 259000.
Good luck, hope you can source them. I love mine and I can let you have the details of the lady I bought mine from if you have no success.
