Where Metro's meet Mosaics internal corner.. - Tile Advice

[Adam18Spring]

Hi Guys
Just a quick one, i have 2 internal corners to do.

The walls either side are in standard beveled white metro tiles 100x200mm

The end 'feature' wall is in 50x150 mosaic metro tiles:

My question is how would you do the junction between the 2? Just silicone the gap?

Thanks

Put the mosaics' on first

As @Albert mosaics first then cut metros to mosaics and silicone join .
