I have 2 questions....how many rose petals do you think I will need for my aisle. I wish I had measurements to give you, but let's just say it's probably about half the size of a church aisle. My second question is where is the cheapest place to buy the silk red rose petals? I found a bag of 2000 on Amazon for about $30, which seems good, but, again...how many total would I need to line the entire aisle on both sides? Thanks for your help!
