Hi NYIS
for me, I use Coreldraw X5..
actually, I didn't have any proper education to use it, but it was pretty easy to understand
I didn't learn how to use it professionally, but at least the basics, such as how to make round, square or even custom shape.
the best thing from this software, you can draw and print with the exact measurement that you want.
for example, if you draw a line with 10cm length on the programme, you can print it exactly 10cm on the paper.
so you won't miss even 1mm on the paper.
after you print the pattern, stick it to a cardboard with paper glue, wait untill it dries and then cut it.
but the worst part is I need to zoom in and zoom out so many times because I only have 14'' screen notebook
I tried on my friend's pc which has 24'' screen, I felt it's easier and faster to finish the pattern.
hope this would be helpful.
Amor.
