I have used both the liquid and the glue stick for various quilting projects. Both work well. I also use another technique that I found on this site from another member. Starch works too. I use StaFlo liquid starch diluted half and half in a spray bottle. I like this better than spray adhesive and less expensive. Around $3 for a 1/2 gallon at Walmart. I am usually in a hurry so I use a hot iron to get it dry. I just finished a Quilt as You Go in panels and the starch worked great for holding the layers together for the quilting. The only problem I had with the starch was that I had to launder my ironing board cover because it was stiff from the overspray.
