I read in a quilt book the other day, instructions to "add starch or sizing" to my fabric and it got me to thinking...I don't really know what "sizing" is and how it might be different from starch. I know there is "sizing" in fabric when I first buy it, and I know what starch is. But I don't know what "sizing" is!
Is it essentially the same thing as starch? If there's a real difference, is "sizing" something a consumer could buy and use, and would I want to use it if I could?
Just kind of wondering if there's a starch-alternate out there that I haven't tried.

(I do still like Best Press very well, but you never know when you might find something better or cheaper!)
