I haven't tried it yet but the Crescent rendr sketchbooks are supposed to be good for blending markers without bleeding through the next page.
Now you can! Best notebook for filling out 100%. Never bleeds to the next page even when blacking out an entire page with sharpie.
this is what i use Rend-R
Doesn't bleed and the pages are thick.
Most of my art is posted here . I usually get it done on a sketchbook. I rarely use blanks but I have a shortbox of blanks I need to use but don't.
I carry 4 sketchbooks with me at a con.
Has anyone used Rendr no show through sketch books/pads?
I've never found the perfect sketch book but I think this is the one.
The exact one i'm trying to find is:

Can't find it on ebay for a reasonable price. This is different to the flat lay one, which has a softcover.
