A home flipper modernized an old fireplace’s exterior with mosaic glass tiles. Does it look too busy? I was at a Realtor home tour this morning and one house had a remodeled kitchen with mosaic glass tile backsplash, similar to this photo. An agent said she had that done to her kitchen and after a month, she and her husband hated it so much they had it removed! The busy pattern drove them nuts. Glass tile in ONE color looks very good, however.
