For shank style buttons, start by cutting off the backs with a pair of flush cutters. Vintage buttons are most commonly made of lightweight metal and plastic so cutting off the shanks is very easy. For embellished collars, make sure there are two sets of embellishments so that the design is symmetrical.You’ll need:
-chambray or denim shirt
-flat back pearls
-Jewel-It washable glue
-a pair of flush wire cutters
-a disposable wooden spoon or plastic container
Squeeze a dollop of Jewel-It washable glue onto a wooden spoon or small plastic container. Jewel-It is the best bonding agent when it comes to glueing hard-to-hold jewels and embellishments onto fabrics. Use a toothpick to dab glue onto the back of a button, rhinestone, or pearl.
Position the embellishment on the tip of the collar and work outwards.
Note that the glue does not set right away and takes quite a while to dry so be careful not to nudge the pieces around too much.
