I starch nearly everything. My quilts come out much much better and the fabric is easier to work with, less stretching and slipping.
It took me a while to figure out how to get enough on the fabric and then how to not get to much.
I now use and old wash tub. I pour in one bottle of starch and two bottles of water. Then I just dunk the fabric until it is soaked wring out and throw in the dryer.
Using a spray bottle of water I mist the fabric the iron. Don't stretch the fabic as you iron or it will distort. Jus press it out nicely.
It is a process but I find it to be well worth my effort.
