Find sketchbooks with paper weight and texture that handle ink watercolor and markers.
For mixed media, choose heavier paper 140 gsm or more with a medium tooth to accept washes and ink without buckling. Spiral bound sketchbooks allow pages to lie flat for scanning and display; stitched bindings are better for archival durability. Consider paper that is cold pressed for texture or hot pressed for smooth ink work. Test a sample page with your usual media to ensure compatibility before committing to a full pad.
