Buying Guide
What thickness should I choose?
Thicker boards (around 3/16″ to 0.23″) offer stronger rigidity and resist bending, making them ideal for large posters and display pieces. For lightweight crafts or small projects, thinner boards may suffice but will be more prone to warping if heavily displayed.
What surface matters?
Double-sided, smooth, acid-free surfaces help prevent paint seepage and yellowing over time. For archival displays, acid-free materials are preferable to preserve artwork and photos.
Are foam inserts or boards better for protection?
Foam inserts excel at cushioning and protecting items in cases, boxes, and transport. Boards provide a stable, flat surface for art and display, with some assortments offering corner protection for shipping.
Which product is best for classrooms?
Multi-pack foam boards and larger sizes are cost-efficient and easy to distribute, making them suitable for classrooms and group projects. Look for models with corner guards and sturdy cores to withstand daily use.
What should I consider for cutting and shaping?
Choose boards and inserts made from materials that respond well to scoring, carving, or cutting with utility knives. Pre-scored or grid-backed versions can help with precise alignment during craft projects.
Storage and longevity considerations
Acid-free, double-sided boards are best for long-term storage and archival displays. If storage space is limited, consider lighter boards that still provide adequate rigidity for your needs.
