Place the second pallet behind the first pallet and mark how high you would like the back of the swing to be.
Remove the wood from the back of the second pallet to lighten the weight.
To make the top of the backrest rounded, use the lid of a can to trace a half circle and then cut the top to a rounded shape.
For additional support, use longer pieces of wood around the entire edge of the first pallet/seat.
Insert eye bolts into the front and back of the seat, and attach chains to them using carabiners.
Lay the pallet flat with the slats that sit closer together facing up. Measure landscape fabric to cover that side.
Staple the fabric down to the pallet working your way across each beam.
Wrap the excess fabric around the edge and staple it in place.
Wrap fabric around the openings and staple it. You can leave the top open if you want to plant tall plants.
Turn your pallet over and fill with a bag of potting mix in between the slats, making sure it is level.
Make little ditches for each plant and set them within the ditch. Scoop dirt in to cover the roots.
Water the plants immediately so as to help pack in the dirt.
You don't necessarily have to do this, but the light color helps to see the tree even when it's not lit.
Carefully pull apart the strands so as not to staple through the wire.
Be creative with this part - if your strand of lights is long, you can make fuller zigzags.
Stapled a scrap piece of pallet wood to the bottom for the trunk of the tree.
