Those are beautiful fella.....going to borrow the idea myself.....very cool scenery.
How are you fixing to the base piece please?
Thanks so much!
I use expanded PVC sheets for my bases (3mm thick), though MDF could work also if you keep moisture to a minimum. When the armatures are ready to go on the base I use either greenstuff or superglue to affix to the base.
Then I apply a light coat of straight PVA to the base and dust it with fine tile grout. After the grout sets hard like cement, I use diluted PVA (50/50) to “seal” the grout in place for good. It wouldn’t hurt to also give all the trunks, branches and roots a thin coating of PVA with a brush before the painting stage. Let that dry. Paint, flock and spray varnish.
