Foundation 01
How Graphite Drawing Works
Understand graphite, clay, pressure and paper tooth as one mark-making system.
Read guide →Foundation 02Graphite Pencil Grades Explained
Use H, HB, F and B grades as a practical continuum rather than a rigid universal standard.
Read guide →Foundation 03Charcoal Drawing Explained
Understand why charcoal delivers broad darks, easy lifting and a different surface relationship from graphite.
Read guide →Foundation 04Drawing Paper Explained
Match paper tooth, weight and surface character to graphite, charcoal and erasing needs.
Read guide →Foundation 05Blending & Erasing in Drawing
Use blending and erasing as controlled mark-making tools rather than automatic cleanup steps.
Read guide →Foundation 06Drawing Values & Edges
Control form by separating value structure from edge softness.
Read guide →Foundation 07Line & Mark Making
Build a vocabulary of line weight, hatching, contour and directional marks.
Read guide →Foundation 08Common Drawing Problems
Diagnose muddy values, shiny darks, stiff contours and damaged paper by tracing the mark-making cause.
Read guide →Practice with control
Use small repeatable exercises so changes in surface, tool or mixture remain visible.
