I always liked den flags and find them useful in developing den spirit and solidarity.
Pretty frequently, I had den opening ceremonies where each den member had their left hand on the den flag, helping to hold it up, while doing a Cub Scout salute with the right hand and repeating the Cub Scout Promise or Law of the pack. So I looked for ways to USE the den flag during activities.
At out June Pack Overnight camp, I promoted den flag making as an acticvity during the camp. Each den made a new den flag to go along with their new den level.
Our district day camp made den flags, but it was a poorly planned activity and used pieces cut out of old Scout Camp tents as flag material. Not too good in practice.
This year, as Day Camp Program Director, I bought good quality, colorful fabric for each of our twelve dens to make their own den flag. I also made up colorful symbols for each den that were printed off on a color copier and which dens could use on their den flag if they wished to do so.
Other printed up Cub Scout symbols and images were provided as raw material for den flags if the dens members wanted to use it. That went pretty well, in my opinion.
However, since I haven't been flogging den flags in my Cub Pack, other den leaders no longer bother.
Do you find Den flags useful, and what is your experience with den flags in Cub Scout packs?
