The Avery glue pen I use is in a white plastic pen casing, the glue inside is blue when wet but dries clear. The glue is in stick form and you turn the barrell of the pen to advance it. The glue itself is only about 1/4 in. wide. Perfect for seam allowances. It is just sticky enough to hold the fabric to the back of the freezer paper while you stitch, but releases easily when you want it to. I have never had to wet the fabric to remove the paper. I tried the stable magic you mentioned but still prefer the freezer paper from the quilt shop, not the the one on a role from the supermarket, it really does make a difference!
