Book Symbols; Chapter Decorations, Ornaments, Fleurons; Separator Lines. Open the Sandbox / Playground link above in a new tab. Copy the symbols you want (one at a time) into that tab. Increase the font-size (see if 200 will work). Then, Alt+Print Screen to copy that window to your clipboard. Paste it into your graphics editor. Crop as needed. Increase the resolution to at least 300. I use 600. Save and then insert that picture into your Book Document.
