This is my first time to try make palm tree leaves.
Next tree i made some parts differently..
i spread the glue more evenly, then its better cut leaves better looking.
Only what you need is glue, feathers and Dracaena marginata plants
First i mix wooden glue 50 % and water 50%
Apply glue.to feathers
glue allows put feathers as palm leaf shape.
When glue is dry you can cut with scissors final shape
i spray base color
i use white pigments and light green to make final leaves colors.
I use Dracaena marginata to make palm tree trunk. I thin at its look very realistic.
Link Dracaena marginata plants.
Then you need only glue leaves to tree.
i am out of feathers... must order more.
only one side have leaves.
Its nor perfect but i hope at you got some idea you own work.
and i think at my next tree is much better than this.
