for the original poster: i heard that the dots are good, ive never used them because i kinda left that area covered in dust, lol. I do know elmers glue is horrible to use..
i'm fairly new too but from what i've learned/heard, acid free glue sticks and glue dots and anything that's gonna come out flat and stay that way (as in not wrinkle up the paper like regular old elmer's glue would) is perfect. people like glue dots because you don't have to wait for them to dry, they're just little dots of adhesive you peel off a roll of paper. they're like $4 for a roll of 200 dots at michael's. glue sticks are on the cheaper side, i think scotch and elmer's make some good ones. michael's also has a cheap glue stick by the brand "craftsmart", you can get a pack of 4 small ones for like $2. they're good too. =)
