I worked on a little plastic dish I could lift away from my work table, so as not to disturb the little pin.
First, tape the back of the pin, like this
some Diamond Glaze in the middle. It will probably "over fill", but
you can always break that part off easily once it is dry.
a pinch of glitter. And now comes the HARD part ! Put your dish away,
and forget about it until tomorrow. It dries slowly because it is in
such a glob. I know you will want to touch it, I know you will. But
off the tape tomorrow, and this is how your little pin will look.
Isn't it so cute ! And only about 3 or 4 minutes of time.
tip is to keep all of your stick pins on a piece of foam. This piece
is recycled, an old piece from a set of brads. I can see them easily,
and of course now that they "stick" in my mind, I remember to use them !
