Edging existing tiles around a serving hatch

LondonJax

We moved into our house 6 months ago and are in the middle of redecorating. One of our problems is the serving hatch between the kitchen and dining room. We don't want to get rid of the hatch yet as it's a 70s house (so looks very much part of the house) and the serving hatch is really handy with a toddler - keeps him out of the kitchen but still easy to keep an eye on!

However, the paint inside the hatch is discoloured and flaking so our next job is to strip that back and repaint it. We have a small, but annoying, problem which we can't seem to solve.

The people we bought off of (one of whom runs an interior decorating company - yeah right!!!) tiled the wall area on the kitchen side of the hatch and cut the tiles to fit around the hatch. But they left those tiles un edged or trimmed. So we have raw, cut tile edges all around the opening for the hatch on that side. The cut tiles come right up to the rim of the hatch all round.

Question is how can we cover the edges? Normal tiling trim strips would be fine if we were tiling the hatch inside as we could lose the fixing part of the trim under new tiles but we're not tiling inside the hatch as it would make the hatch area smaller and door fixings would have to be realigned. As we're renovating the kitchen once our little one is over the "let's crayon on every surface" stage:rotfl:we just need something that will look decent for a year or two then we'll be taking all the tiles down anyway.

What we need is something that will lie flat on the wooden surface of the serving hatch, going over the tile edge like a small shelf - don't mind if the "shelf juts out 0.5 cms or similar OR we need something that will fold or fit over the tile edges and run onto the wood of the serving hatch (a bit like laminating a worktop edge if you see what I mean)

Any ideas?

The tiles, thankfully, are white (I believe they are Metro from B&Q) if that helps.

Any suggestions very welcome!

Thanks
