I too am shouting the benefits of glue from the rooftops!! My last quilt turned out with perfectly matched 4 patch squares! I was totally elated at how precise it made them! I was using a washable glue stick and it was messy, I just used the very edge of it along the seams and it worked ok. I will invest in a bottle of washable glue next time to ease up the messiness of the stick on my cutting mat. But, I have to say that glue works like magic to ensure your points and seams come out perfectly precise!! YIPPEE!!! I am a perfectionist so this little technique is my new best friend! lol
