How to make sturdy cardboard crafts that last

When teacher Sarah Johnson tried making a cardboard dollhouse for her kindergarten class, it collapsed during show-and-tell. "The kids were devastated," she recalls. The culprit? Weak corrugation and poor joining techniques.

According to the 2023 Sustainable Crafting Report by EcoArts, 68% of failed cardboard projects stem from structural issues. But the solution is simple:

  1. Identify "double-wall" cardboard (look for two wavy layers between sheets)
  2. Apply white glue in zigzag patterns for maximum adhesion
  3. Reinforce corners with masking tape before decorating
Pro Tip: The UPS Packaging Lab offers free guides on cardboard strength testing.
