Flip your stencil over so that the 'back' is facing up. Spray a very thin layer of spray adhesive over the back of your entire stencil. Wait for it to dry slightly before flipping it back over and attaching it to your glassine bag. The spray adhesive should be tacky to the touch before applying the stencil to the bag.
