If it has no varnish, light sand then oil. If varnished very good sand using a electric sander, medium first sand then finer the second sand, wipe down to get all dust off then oil. If you use a combo of linseed and turpentine make sure you use gum turpentine. Use more turpentine to start off as will penetrate the wood better. Good luck

What a beautiful room, table is great, I love transparent furniture also it could work well with your room, I can imagine it with your table but a more luxe look could be stainless to blend with benchtops or leather or be brave and mix it up for a more contemporary look, depends on the style you are after, fab room

Hmmm I do understand your indecision. So if it were me I would lean toward caution and choose a tabletop which blends with your existing colour scheme. It's always difficult to tell from a photo the hues in someone else's home. It does appear your kitchen tiles are a cream colour, and possibly your sofa is a warm white. Is that correct? If so, I would look for a marble with warm tones. If you like black as the main colour, is there one with beige or warm white or brown tones in it? Otherwise, you cannot go wrong with glass topped or timber.

Try the Amazon Australia site. If placemats only come in sets of 4, then purchase two sets. Love the colours in the placemats Kate has shared.
