I've started constructing some espaliers for the back scene wall on Gneiss Cider. They're made with a German plastic deciduous tree for N/Z scale.
Two of the plastic trees are needed to make up a single espalier.
First photo (2nd espalier) now shows first step in the construction process which involves adhering the two main branches of tree to create a thicker trunk. Trunk is then covered in Vallejo modelling paste.
I've used florist wire between the two trunks to provide a substantial 'leg' to fit into baseboard.
Addition of a brown crepe tape wrapped around the paste, adhered using PVA.
Next step is to paint the espalier prior to adding leaves and apples.
