Any water-soluble glue will work, like Elmer's school glue. I use a liquid glue stick from Office Depot. Roxanne's Glue Baste It seems to be a favorite because I've heard the tip doesn't get goobed up. Glue Sticks that are water soluble work. Some like the ones that glue on purple and dry clear, so we can see where the glue is. Dry the glue with an iron before sewing. Makes the fabric stiff as a board if too much is used, but it really does wash out.
In this year's BOM, we learned to use glue instead of pins, when piecing with tiny pieces. It works really well.
