At ABLESIA we don't have a specific rule that makes us package our products always the same way. Instead, we like to use what packing materials (previously used) we have on hand. We like to reuse old cardboard boxes or made our own packages from cards or paper that we already have at the studio.
Here at our small studio, we like to reuse every single thing that we can.
We like to keep used or printed sheets of paper to re use again. We use them for drawing or taking notes where possible.
Small plastic pieces that we sometimes receive are used to create pockets for shipping labels or even to draw cutting patterns our from (for example a hat pattern) that we really want to keep for a long time.
