i don't understand the comment about silk deteriorating- since there are silk garments (quilted garments) in museums that are literally thousands of years old-
silk is stronger than cotton
the dream silk batting from the dream company is a wonderful batting- it drapes beautifully- feels so (silky soft) when working with it- needles wonderfully...is a dream
all of the batts from the dream company are a joy to work with- the dream orient (which is a silk/bamboo blend) is really great- dream wool (my favorite) the dream green, dream poly and yes even dream cotton are all great batts to use. just follow the recommendations on the package for quilting distances, and care instructions and you will not be disappointed.
