Rose petal aisle runners are beautiful and classic, but unless you're a florist, you may not know just how many petals you need to achieve the look you see all over Pinterest. That's where Petal Garden's "Petal Quantity Calculator" comes in handy: input your coverage type, area and aisle length, and it spits out just how many petals you'll need to achieve the look you're after for your wedding.
