I don't starch heavy. Like before I only make enough for the task at hand. I spray lightly and let it sit for a short time only while I spray the rest. Then go back and iron the first piece then the rest in order. If after ironing the pieces, I don't have enough time to get right back to them, I put them into the project box or a sealed container of some sort and label it. If it's sealed you don't have to worry about any bugs. Since I don't use dryer sheets when prewashing I don't worry about the bias much. That is why don't heavily starch any fabric. When I dilute the starch, it's usually an ounce of Sta-Flo to 4ounces of water if that much.
