rayon thread

http://www.fibersource.com/f-tutor/rayon.htm

Will tell you lots more than you want to know about rayon/viscose fiber. But
it is pure cellulose (the same basic component of cotton and all plant
fibers) made from wood pulp.
quote from the site:
General Rayon Fiber Care Tips - Most rayon fabrics should be dry-cleaned,
but some types of fabric and garment construction are such that they can be
hand or machine washed. For washable items, use the following as a guide:

a.. Fabrics containing rayon can be bleached; some finishes, however,
are sensitive to chlorine bleach.
b.. Use mild lukewarm or cool suds. Gently squeeze suds through fabric
and rinse in lukewarm water. Do not wring or twist the article.
c.. Smooth or shake out article and place on a non-rust hanger to dry.
Rayon sweaters should be dried flat.
d.. Press the article while damp on the wrong side with the iron at a
moderate setting. If finishing on the right side is required, a press cloth
should be used.
e.. Between wearings, rayon articles may be pressed with a cool iron.
(For specific instructions, refer to garment's sewn-in care label.)

Ok I went to JoAnn's to get the thread for my baby quilt. I couldn't resist
the variegated thread in the bright red, blue, green and yellow. It will
match the quilt perfectly. However, it is 100% Rayon. Now I'm no expert on
thread. I've nearly always just used what I had on hand. Mostly cotton
though. What is the difference in Rayon thread and cotton thread? Will the
Rayon thread be ok to use in the baby quilt or not? If not, I also got a
spool of light blue that I can use. After seeing it though, I really do want
to use the variegated thread. I'm doing the horizontal lines going the width
of the quilt 2" apart and the diagonal lines from the upper right corner to
the lower left corner 2" apart. I'm please with how the grid looks.
