Thank you for your question. If you need any clarification, please
don't hesitate to ask.
According to a January/February 2004 Newsletter from C&R Scrapbooking,
a retail scrapbook company, fabric is indeed acid-free and suitable
for this application:
"Fabric (cotton, lace, embroidered badges, tassels, shoelaces, ribbon,
and more) is safe for your scrapbooks. Fabric is acid-free and needs
no interfacing or encasement. Even synthetic fabrics such as
polyester or rayon pose no threat to your photographs. You can also
add string, yarn, felt, and ribbon to your list of safe accents to
use. Even most raffias are colorfast and safe."
However, ribbon might have acid added, per an article on another scrapbooking site:
To Ribbon or Not to Ribbon
"Let?s first talk about acid. Ever since I first started to scrapbook,
I was told that all fabric is acid free. I?ve come to hear just
recently that sometimes when ribbon is processed, acid is added.
Offray ribbon is acid free as far as I know. Any other ribbons should
be tested with an acid testing pen. These can usually be picked up at
your LSS. As long as your ribbon is acid free, it doesn?t matter where
you put it on your page, it will be safe for your pictures. If there
is acid in the ribbon, and you would still like to use it, be careful
not place it where it will touch your pictures. The acid will destroy
them. Making sure your pictures will last is very important!"
