i'm working through md tutorials (many which are super fun!).
i'm just wondering in many of the tutorials - why near the end of them, you always duplicate almost the entire pattern via layer clone?
e.g. in the elasticated pants tutorial, why do you duplicate all the pants body and add slightly different weft etc.
- why can any effect not be done with just the original pattern layer that was being worked on? what does duplicating the pattern layer get us / help us achieve?
- same question when using pressure. why in tutorial examples are the pattern layers duplicated (via layer clone-over for example) when adding pressure. what's the reason for not just using pressure to cause puff using a single original pattern layer?
thanks for any help / tips!
