I use Niagara in the non aerosol format, works great. I only use it when I'm going to use the fabric and I wash my finished projects as soon as they are done, no bug problem. I do however have scraps that must have it on it, no bug problem there either. No humidity here so maybe that why. I also think it works better than Mary Ellens. Mary Ellens is just too expensive for me and don't like paying that price and don't like any of the scents either.
Some of the "quilt police" types think using starch is just so yesterday. They also think I'm crazy for loving my Viking D1 since they believe Janome is the only machine to use. Interesting that they don't understand why I don't ever have a tension problem. To each his own.
