You were wondering how we ended the pencil liner in our subway tile backsplash and where to get bullnose pieces. For our tile, we actually had to custom order the pencil liner, including the bullnose pieces, and have it cut (although I vaguely remember that this was because we used 1/4" liner, and if we'd been willing to use 1/2" liner, we could have gotten stock pieces). We got ours from a local tile shop; I imagine many tile shops could do it (but if not, ours might well be willing to ship).

Hope that helps you (or anyone else looking for pencil liner info)--good luck with the renovation!
