Get everyone's input and design a pack patch.  Order them in quantity.  Parents earn these patches (mostly for their Scouts) by completing their pack job.  Every family should have a job.  Pack and den leaders, committee members, event chairs and lots of other jobs like telephone chair.  Have multiple chairs for big events.  For example, Blue and Gold could have a food chair, entertainment chair, decorations chair, and general chair.  At the first Pack Meeting, show the patch and award to the Cubmaster and Den Leaders plus a chair if completed.  At the second Pack Meeting, award to Assistant Leaders and chairs.  At the third Pack Meeting award to the committee and to chairs.  At every pack Meeting, thank parents and present their patches.
