Translating directly between sign languages could support communication across signing communities without requiring a shared written language. A cascade of sign-to-text, spoken-language translation, and text-to-sign models offers one route, but can propagate intermediate errors and requires three sequential translation stages. We develop direct sign-to-sign translation, whose training is limited by the scarcity of parallel signing across languages. To address this obstacle, we adapt back-translation to construct cross-lingual pairs from existing text-sign corpora: the source signing is
