Wall-friendly glue:
2 Tbs. cornstarch
1/4c. cold water
Mix well then add
2 c. boiling water
So then I submerged my cutouts in my glue and then squeezed them out. Press the top edge of the design up against the wall and then squeegee down with the side of my hand, pushing out any air bubbles. But ...I really wanted something else. So I added my cute little bird. Voila!
