Oh my goodness Lizzy, sorry you're having such a problem. I don't know how to help with this but have you tried using a glue stick rather than school glue? The Lapel Glue Stick from MSQC is my favorite & it's temporary but I've also used the Dritz Fabric Glue Stick & it works well, too. I've never had a problem with glue on my needle or anywhere else & I love them for when I don't want to use pins or clips.
