I just found a good resource here: Tilly and the buttons. You will find a guide for beginners with no background in sewing to get you through the first steps of sewing.
Oh, do not forget to read the directions of the pattern before you start. American pattern mostly include the sewing allowance, European and Japanese pattern do not include it and you have to add it yourself.
I use sewing chalk or old soap bars to mark the fabric.
