Can I attach a piece Velcro to the back of a cell phone (plastic?) with Elmer's glue?

To attach a metal comb to a veil using Velcro you would need the Velcro on the band of the headpiece and then use a good glue from a craft shop such as 'Michael's Crafts' and use one-sided Velcro (one side smooth) and use the glue on that side to attach to the metal. Be sure to read the label of the glue to be sure it will stick to metal.

To fix worn-out Velcro, first clean both the hook and loop sides with a lint roller or a soft brush to remove debris and lint that may be affecting their grip.

If the Velcro is too worn, consider replacing it entirely by sewing on new strips or using adhesive Velcro patches.
