Not only is this easy to make, but inexpensive, too. You probably already have the ingredients on hand. I didn't bother using organic flour for this because it's not like I will eat it, but if you prefer to, you can.
I've always wanted to make my own glue. I thought it would be pretty cool to personalize it by adding, glitter, etc. But, this time I made it plain, since I use white glue most often. To store the glue, you can keep it in an old glue bottle or any bottle that will be able to squeeze it out.. I stored mine in a mayonnaise bottle.
