Description

Join the November 2025 Painting Best Practices Cohorts session for a focused look at how supports, grounds, and varnishes shape the long-term behavior of oil paintings.

In this live Zoom meeting, George O’Hanlon will review key findings and practical recommendations from four recent Painting Best Practices articles:

Staples vs Tacks—Canvas Attachments and Strain in Easel Paintings
How different fasteners, placements, and spacings influence strain, cusping, and cracking in stretched canvases, informed by ESPI strain mapping.

Oil Painting on Paper: Interaction, Damage, and Best Practices
How oil interacts with paper; when and how to use sizing, grounds, and mounting systems to avoid halos, embrittlement, and structural weakness.

Oil Painting on Wood: Selecting Wood, Protecting
