I personally would but the "cotton Seeds"to the back so if the seeds do leak the oil that is in them then it will show on the back and not the front of the quilt. I was taught not to use cotton backing with too many seeds due to the seeds can leak an oil. (warm and natural) More seeds can be left in the cotton batting due to the mechanical manufactureing process than when the seeds were hand plucked as they used to do many years ago.
