Good designers have their designs copied. It's a story as old as time but lately it's been happening to many of my designer/musician/creative friends.
I have also been affected on more than one occasion by a 'designer' deciding to borrow an idea or two.
It's disrespectful and quite honestly tasteless to take someone else's design/idea/pattern/product name and pass it off as your own brain child.
It's wrong, makes you look like a shameless 'copy-cat' and causes more trouble than it's worth.
If you are a real 'designer' then I'm sure you have it in you to come up with your own original designs/ideas so go on, get busy and maybe one day we'll see you in Selvedge Magazine.
