Getting the true "ebony star" at least in my experience was damn near impossible. The local kitchen and cabinet makers said it was discontinued and there were no offcuts at all around where I live. I was given some other textured laminate which I've since made a ring out of but haven't finished putting it back together to test yet. I have a feeling it's not going to be that great though so I may end up trying the lazy susan method. Probably not ideal but if I can't get a good enough ebony star replacement I have no other option.
