speaking of drafting paper & blue prints

[bikeman564™]

I'd say most of the time I used vellum or bond paper, then a few times used mylar. Drafting on mylar was fun and required a specific lead type. Vellum is thin, and care needs to be taken when erasing.

Blue prints are cool I made some from stuff I drew. Interesting process. The paper that is turned into a blue prints is light sensitive and is kept in black plastic bags until its used. mmm ammonia

Growing up, my favorite store was a stationary store.  You went there to find drafting boards, triangles and stencils as well as paper, ink, pencils and art supplies.  All of mine are gone now like most of the hobby shops.

Vellum is all I ever used.  My first job was in a department with about 25 drawing boards and a large blueprint room.  My board was right outside the blueprint room door.  I have fond memories of the ammonia smell.

I love art supply stores...I enjoy wandering around in them whenever there is one near by in any city. I do buy supplies when I get the chance.

Blue PRINTS or Blue LINES?

yeah, one of dad's pet peeves.

Once I got out of high school, it was mostly mylar.  Be REAL careful erasing with an electric eraser!

Anyone use Crolux to reuse existing drawings for new designs?

yes

is the difference in how they were printed?

The process was the same, but backwards.

Originally, the prints were blue background, white lines.  Pretty old and rare.  Someone quickly  figured out how to reverse that and make the paper white and lines blue,

Yes.  The older blueprint process used a negative paper process.
