Choose a design that fits the time you have. A narrow bookmark is easy to finish in one sitting, while a small set of themed pages gives you room to revisit the same color palette.
Coloring bookmarks
Color the sheet before cutting out the bookmarks. Plain paper works for a test print. Use printer-compatible cardstock for a bookmark that will hold up to regular handling.
Foldable mini coloring books
Read the folding guide before cutting the sheet. If the page order looks unusual on the printout, fold a plain test copy first to see how the pages line up. Color before folding if you want a flat surface to work on.
Pick paper for your coloring tools
Colored pencils work well on ordinary printer paper. For markers, try a small patch first and place a scrap sheet underneath to catch bleed-through. Check the printable’s paper size and preview the margins before printing.
