unit 121- tutorial chair

The chair wasn't hard however i kept deleting my model by accident or it would simply disappear so i had to restart my model many times.
The next thing i had trouble with was creating the curved edges for the seat. For some reason it wouldn't do it for me so i had to try over and over until it did work. I also had trouble finding the button to do the action.
The extruding for the legs and back was easy for me as i had already done something similar in an other 3D package.
