It's always chancy, in my opinion, to mix poly with cotton in a quilt. I don't mind using it in
other craft projects but not mixed in a quilt block. Sometimes you can get by without any
problems but not usually. At least that's my experience. I don't like having to starch because
there's no guarantee that it will stay straight after it's completed and washed. Then you'll
really be unhappy that you spent time, effort, and money on a disappointing project.
