Love this look. I would add hanging Swarovski crystals for a added sparkle.
All you need is:
12 Stems of about 7′ Tall curly willow branches
10 Stems of medium curly willow branches
1 Large bag of sand
2 large planters
Twine wire
Wire cutters
Sheet moss to cover the sand in the planter
Add some flowers and you have a beautiful inexpensive arch!!!!
