I use a lot of spray starch. It really helps stabilize bias edges and piecing.
I use Sta Flo and mix it in a spray bottle from the gardening section of Wal Mart.
A couple of years ago at my quilt retreat, someone complained about the canned spray starch bothering their allergies. I went to WalMart and picked up a jug of Sta Flo and have used it every since. I love it!
