Fresh pine needles are used in a variety of ways for the processions and floral carpets; I’ve even seen them sprinkled on the floor of small stores and in homes. These pictures are in Antigua of the venders selling the pine needles.
In Panajachel the pine needles were used as a base for the decorations of fruits, vegetables and flowers in the alfombras. The rain started a couple hours after these floral carpets were made so they didn’t last long.
On the ride from Antigua to Panajachel we saw this pickup truck loaded with palm branches to be used in decorations or in church services for Holy Week.
