I have some starched (with glue) snowflakes that have pin marks left on the white thread used (yes, I used galvanized pins). I have tried to put more glue on top to cover the marks but it doesn't work. I've tried the white paint in a bottle you get at craft stores that can be used on fabric but that doesn't work either. My sister covers hers up (when it happens) with glitter glue. I don't want to use the glitter glue, does anyone have any suggestions?
