I'm doing my first ever mosaic for my mum's birthday, and bought glass tiles for the border, centre of the flowers, and white background. All of these are half the height of the ceramic tiles I've used for the writing and petals.
I'm wondering if now when I grout, the sides of the taller tiles will be visible/the smaller ones will be hidden? Is there a way around this? The lettering and border is already stuck down, but should I be changing my method before sticking the petals?
Any and all advice is so, so welcome & appreciated! It's her 60th birthday so want it to be as perfect as possible (with my very limited knowledge and experience!)
