"Then to make the starch, pour hot water on some white powder...." peter made this comment in my posting on laundry blue.
when we were in primary school, during our art and craft lessons, the glue we used usually came in a tube like a small tube of tooth-paste or a small bottle-like container. back at home when we needed to do any sticking or glueing, we would make use of the starch that our mother used for starching clothes.
how do you prepare this home-made glue? those days, my mother used tapioca flour - peter referred to this as some white powder - to make this starchy substance. you can use any vegetable flour. for the picture in this blog, i used some left-over potato flour.
first, you add some tap water to the flour and stir it until it becomes a thick, milky solution. then you add hot water to it, a little at a time, and continue to stir very hard and fast. the opaque solution will gradually become clear. when the paste becomes transparent (as in the top picture), you stop adding hot water.
the paste, if it is going to be used for starching clothes, should not be lumpy. when you want to starch the clothes, you scoop a handful of the starchy paste and dissolve it in a pail of water. then you rinse the clothes in the pail of starchy water. the clothes, when they are dry, will become stiff and this makes ironing them easier.
nowadays, the fabric starch comes in the form of an aerosol spray can. it has brightener to give your clothes that smart, crisp look. it is supposed to help remove creases and wrinkles on your clothes. however, it cannot be used on silk and other delicate fabrics.
for glueing purpose, if you want the 'glue' to be thicker, then you do not need to add so much hot water. the paste will be lumpy but it will stick better. if you want to keep the glue for sometime, then, instead of using just hot water, add some vinegar to the water.

today, hardly anyone makes use of the home-made starch. you can get glue which comes in handy containers or in the form of a stick.
