You ladies are so good at finding stuff. My stairs were carpeted when we moved in then we had our hall tiled. Tiler was very good and in trying not to get adhesive on the carpet has left a small gap between the tile and the carpet on the bottom step. It doesn't really bother me but thought it would look nice if I could glue some sort of moulding on the edge of the tiles, however the bottom step is rounded so the moulding would been to be flexible. Any ideas ?
