I saw an article recently about making mushrooms and decided to show you my own cheapest approach.
Materials you will need:
Grape stalks (grapes can still be attached to provide a yummy snack while you work)
Modelling clay (Milliput, Greenstuff, Air drying clay etc.)
What to do:
Remove grape from stem and eat (if it hasn’t already been removed).
Cut off ends of stalk and trim any excess. Leave to dry.

Roll a very small amount of clay into a ball.
Indent one side of the ball with a pointy object. I prefer the end of my 3.5mm headphone jack.

Press dry stalk into indent to form a smaller indent for glueing.
Wait for clay to dry…
Glue the two bits together and paint to your prefered colour scheme.

Nice and simple, grape stalks are a genius idea! Way more texture than bits of tooth pick and easier aswell.
