It's like tracing paper, but a heavier weight while still being 
transparent.

I've seen business cards printed on /card/ thickness paper that's 
still transparent like vellum, but I've never seen it for sale on its 
own.

If you search, don't get drafting vellum paper mixed up with 'real' 
vellum, the term originally being used for specially treated animal 
hides used to create illuminated (gilded) calligraphy manuscripts. 
Animal hide vellum is rare and expensive these days.
