Liking the lichen

(Apologies for the cheesey title - couldn't resist)

Found some interesting patches of lichen on wooden posts on a recent trip to Dobbies (with the parents, I must stress!). Love the detail within these photos - the colours, patterns and texture. Could be an interesting project to try and reproduce in stitch? I like the idea of distorting the scale, for example by enlarging an area to make it less obvious what it is.

I like being able to see interesting details in something that is normally overloooked.
