I’ve been fielding a lot of questions lately regarding where to find liquid starch.
First using starch is not a necessity for making papier mache paste, it’s just my preference so if you can’t find it don’t sweat it.
Liquid starch is available in the laundry detergent section of most grocery stores, or a least it is in my area.
The brand I use is called Sta-Flo concentrated liquid starch and runs about $2.70 for 64 fluid ounces.
It is also possible to make your own liquid starch by mixing corn starch and boiling water, this is a recipe I found via Google.
1/2 cup cornstarch
1/2 cup cold water
Mix and keep stirring while you pour in about 1 1/2 to 2 cups of boiling water depending on how stiff you need.
It should stay clear.
