i´m no pro at this..but can´t you try to drill the same way one drill in bathroom or kitchen tiles?

Lovisa

You need a diamond drill and also need to cool the plate down with water while you drill. And depending on if the plates are porcelain, earthenware or stoneware, it´ll be more or less hard to drill. Too hot or too forced it´ll probably crack.

The easiest and hopefully also nicest result you would get by asking a potter to throw new plates for you, with holes and all. I thiiiiiink there should be some potters around here somewhere…..*looks around*

Thanks all… I'm searching…
