Mixing concrete

WALHT create a substances that is strong enough to make structure. This could 

be accommodate  animal or a group of people or even hold up a fence post.

I learnt how to make concrete using different ingredients like bark clay dirt  black sand.

What I found easy was the pictures. What I found hard was the information.

What I would try next time is to make it by inserting different things.

Modifying an image

I learnt how to modify an image for reuse.

I learnt how to use polyline and add call out's

It was really hard to use poly lining  because if you
made a mistake you had to start all over again.

What I found hard was poly lining and what I found easy was
adding call outs.
