When I was young, I'd put little braids in my hair then glue rhinestones to the braids for sparkles when I'd go out at night. This would be wonderful for a child's fairy or princess costume at Halloween!
To remove them, simply wet the hair in the bath while the child plays and wait several minutes for the washable glue to dissolve (about 5 minutes), then wash hair as usual.
