Since there are several posts about starching fabrics and how everyone does it, I will just share what I learned about Guild about that.l Be sure to use Spray Sizing as the bugs won't get into the fabrics like they do starched items.
I have used the sizing for a long time, and have never had a problem with silverfish, bugs, ect.. It is also very cheap and gives fabric a nice finish. I get it at Wal-Mart or Dollar General, but suppose other stores have it.
