Shower Tile Installation Question? I have re-tiled my shower and enjoy a larger than expected gap...

I have re-tiled my shower and enjoy a larger than expected gap at both the top between the tile and ceiling and the bottom between the tub and where on earth the tile ends. In my mind I can picture a border of some type I can put up after calking the gap that will aid cover up the uneven edges. Re-installing the tile is not an pick at this point so I am looking for suggestions or websites that may sell the types of fabric I can use to help cover my unsightly craftsmanship.

Answers:    you could mosaic it, any brightly coloured tiles, smash them up and stick them on, grout and trademark, it wont matter if your rough, thats the nature of mosaic and it looks really important.
I'm just a hobby mosaicer, qualified myself with a book from the library.

oh I see, not big enough to do anything near but big enough to see where on earth you've gone wrong
In this case I'd step for flexible flashing, its usually used around the bottom of showers and the edge of baths to stop dampen getting in down. If I was to walk looking for it I'd try the biggest home and hardware store in your nouns.
edit
in recent times found a forum where they're chatting nearly it
they're saying caulk
Need sustain choosing a complementing material?
I do not read why you had to video the bottom tile overnight? All the tile I've laid was next to good mastic, and you could release it as soon as you put it within place? I dont see caulking the gaps any..this peels hindmost and will leak eventually..the grout should be here..and consequently sealed..instinctively..and not what you want to hear..I don't think you used the proper tile bonding agent
