"We used tacky glue instead of glue dots to put together so it took a little longer to dry. This was OK because it gave the children time to look for books and other materials at the library to take home. Back was a little flimsy, but we folded the napkins in half, triangle point up, so you could see the "sky" on the back also. Kids had a great time and were proud of their project. No frustrated parents, also a good thing!"
