I use 100% cotton, heavyweight (300 g/m2), mould made, archival, chlorine and pH neutral / acid free papers, guaranteeing long conservation and inalterability over time.
The rags I use almost exclusively is watermarked Fabriano Artistico, this is internally and externally sized watercolor paper, brilliant white without optical bleaching, with no animal by-products used.
Dating back to 1264, the Fabriano mill’s fine arts papers were used and highly praised by Michelangelo. Nowadays, they are committed to renewable energy and make extensive use of self-generated hydroelectric power.
I love rough texture, but sometimes I use cold press watercolor paper as well.
