To make hanging easy. Always check the recommended soakage time on labels. Paste strips, then gently fold paste to paste, fold over again. Leave aside to become supple for the recommended time and be watchful that all strips soak for approximately the same time.
__Roll Coverage__ It is possible to achieve 4 drops per roll if there is no matching (plains or stripes) and minimal waste. That’s 2m (6ft8in) wide of wall per roll.
