Hi There,
I found a source where one can download free drawing borders with no conditions. DWG and IGES file formats, first sheet and following sheets, in all sizes from A to E available. I reviewed the B size and it looks good enough to me. Even if you must edit to achieve exactly what you want, these are a great start. Enjoy.
