Add cutting-line to text

May i steal some advice please..

I bought a Roland VP540 and dont know it at all as my previous was a Lexmark. I want to make a sticker, let say a letter A and put a different colour border on it... and then i have to add a cutline. How do i do it as previously i used the border as the cutline but that means i cant add a fat border on the letter. Please advice..

Thank you,
