Since Elmer's white glue first hit the market in 1947, the number of adhesives available has grown almost too large to count. But choosing the best one for a particular job is easy when you understand how glues work and how to use them.
Often, more than one type of glue can be used for a project. To select the best one, consider its setting time, ease of use, and special characteristics. Other things to consider are how a glue ages and its toxicity. Rubber cement, for example, yellows papers and photographs over time, even though its suppleness makes it good for things that move, like pop-up cards; your task will dictate whether you can trade some flexibility for the stability of an acid-free glue stick, which won't discolor. Toxicity is always a concern, especially around children; safety levels range widely, from epoxies that must be kept away from skin to pastes that are not harmful even if ingested.
