To make 1:1 patterns in ink is nonsense unless you will hang it on the wall like a picture.
But stamping them is not ? I fail to see your logic there... You like to stamp, I like to ink. Be kind to a young man's fancy
The whole pattern does not need to be inked : the lines where you cut are cut out anyway. A few lines only would be inked, such as darts, pockets or grainline. And all the writing, which is the whole point.
And it serve no other puropose than to make something nice. Today, I use only pencil, and it is enough (for bench tailoring. Manufacturing production patterns are a whole different topic).
