Local (well for those of us in Alaska)
Blaines Art carries both Adirondack and Pinata ink along with
YUPO, tiles, frames for tiles and painting accessories plus classes.
Frames for Tiles:
Here are some wonderful little tile frames I like. I have found it is useful to get the backs that are enclosed as it has a neater and more professional finish.
