Glues of different kinds

 What is contact adhesive? A strong glue which needs two piece to come into contact with each other.

Glues start with the weakest and simplest glues suitable for positioning paper. Some allow you to slide the top piece around and get it straight long before they set.

Paper glues are often like roll on deodorants in small sold sticks at small prices from craft shops. You can wind them up by twisting the base like a lipstick, without touching the glue. Advisable to wear an apron and place an important piece of paper below. Practise on an unimportant objects. Wipe your fingers before touching the front of any drawing or photo.

Shoo goo.

For shoes you want glue which won't pull apart. But you don't want a glue which sets so rigidly that your sole of your shoe cannot flex as your foot bends as you walk along.

Next we come to tougher glues. 

Evostick

The strongest glues stick firm. But you don't want them to glue your fingers together. Nor to glue to the table top the item you are repairing on constructing.

To prevent any danger of making a mess on a precious work surface, it is a good idea to use these stronger glues outside and not on a precious work surface. You might want to wear old clothes or overalls or protective gloves or use tongs.

You can also buy spray on glue. Not cheap. About 20 US dollars.
