Simple protective overlay:
IDEALLY you will want to use Acetate for this as it will
protect from weather and fingers and will not require being lifted
to view your work. Unless it's boarded it will
not provide much more than moisture protection. You can board
it and do this overlay instead of wrapping it as well.
A cheaper route than Acetate is "parchment tracing paper".
It will protect from oily fingers and stray water drops, but is more
economical as it comes on cheaper pads.
I'll exlain what parchment tracing is now as people
have very set ideas what "parchment" is, and they think tracing
paper is like delicate tissue paper. Not true, this kind of paper is
very thin, fairly translucent, but hard - thus the name parchment.
The name "parchment" in cellouse papers (not hide) refers to a stiffness
and surface hardness (as animal hide parchment is both stiff and hard).
There are varying thicknesses of these transculent parchements. "Tracing"
is typically the thinnest.
Parchment
Tracing paper pad
the bigger the better, possible multiple scrolls from each sheet
Bienfang 100fine is what I like, but it's not as cheap
as the canson, etc., but it does come in larger sizes like 14x17 which
you will need. You can get 100 sheets of that size for $17 which is
not a expensive investment on your work when you think what it comes
out to per sheet and per scroll. 100 sheets will last you a long time,
and that size should cover a wide variety of sizes you do.
AGAIN: Parchment is a simpler protection than
acetate. I recommend the the below method acetate as it will provide
rain protection, parchement will only keep back a drop or two of
rain off, or guard against sweaty hands.
I only show this method here as a cheaper/simpler alternative
to full out boarding. If what you are making a scroll for is an outdoor
event or one you extremly worked hard on, has lot of gold work, etc,
use the boarding method.
