I guess my questions were not as understandable as I wished - ....
"Does one work better than the other for different sewing?" I meant, Are there circumstances where the glue stick may be better to use as opposed to using the liquid? example - Would you use the liquid to "pin" down a smaller piece of fabric as in applique and perhaps use a glue stick for "pinning" lengths of fabric as in borders, or binding?
"Does anyone use it for applique instead of starch?" In applique, where the edges are folded under and then sewn, it is common to use liquid starch and apply it with a brush or Qtip to the under turned edges so that they "stick" underneath. This makes sewing easier and quicker whether by hand or by machine especially for smaller, finicky pieces. I was wondering if anyone has used the Elmers glue for this purpose and possibly make the process easier and faster than using liquid starch.
I am thinking that since the glue is concentrated starch and if only a little bit is used that it could possibly be used for smaller pieces when doing applique not only to hold the edges but also to hold in place.
