Frequently Asked Questions
What is pattern repeat?
Pattern repeat is the vertical distance before the wallpaper pattern repeats. It determines how much extra length each drop needs for pattern matching.
Should I buy extra rolls?
Yes, buy at least 1 extra roll for mistakes and future repairs. It's hard to match dye lots later.
