I use Glue Sticks for all my applique work. I love it because I can pick up and move around any piece that is not in the just right position for about 30minutes before it sets firmly enough for me to machine applique it. Once set it doesn't gum up your needle either. I hate the stiffness that the different heat bond products can give items.
I use "School Glue" all the time to baste my quilts after I first heard people talking about using it. I've had no problem washing it out using plain ol' water and laundry soap. I wash all my quilts in cold water and that doesn't effect it being washed out either. If you get it on too thick, it can be a little hard to sew through. Like I used to tell my students, "Just a dot, not a lot"
