We've just discovered Patternbank Studio online https://patternbank.com/. It's an amazing resource for all things print, pattern and graphics. The best designers in the business upload their patterns for people to use for personal or commercial projects in exchange for a small licence fee.
We've just bought this Distressed Medieval Damask pattern by Kathleen Ney. She originally intended it to be used for wallpaper but we have had it printed locally into wrapping paper. So we know it's completely unique. What a brilliant way of supporting the creative industry and getting unusual wrapping resources. We'll certainly be using it again!
