Hi ecmorgan,
The rolling ruler doesn't have to be the brand in the video, any quality
make will be fine. The more durably constructed types with metal rollers
and rubber rings are better and will last.
Also, this site is good If you want to perfect your handwriting....

Can't see through the 110 lb archival paper? Try....
(a) Removing the Clark Kent specs, or
(b) Have a look at the archival 'Vellum' papers made for calligraphy.
These papers have nice subtle tones that will set off the stamps nicely.
(c) If you have a lightbox you can use this to see through most papers to reveal 'what lies beneath'
