Those are lovely! were they hard to make?
Not at all! I'm big on multi-tasking and I can't sit still to save my life...so I made these all while watching a movie. Just trace, cut, and glue! Voila
To answer the glue question: I used a glue stick on most of these and they are holding up really well. Superglue might be a little too heavy duty for the catalogs, but I'm sure it would work fine, too.
