Multi-Level Matches
Check out other badges that might work well with this badge when doing activities with multiple levels. These are simply suggestions and may take some creativity and extra steps to earn all the badges in various levels.
A Multi-Level Troop will need to do extra steps when earning different badges across levels. It depends on how many requirements overlap. Some will only have one or two matching requirements.
If there is no badge in a level, we suggest that a level earns a Fun Patch related to the rest of the badges instead of an official badge.
- Daisy – Model Car Design Challenge could be adapted
- Brownie – Race Car Design Challenge

- Cadette – Fun Patch (no equivalent)
- Senior – Fun Patch (no equivalent)
- Ambassador – Fun Patch (no equivalent)
Uniform Vest Placement
This badge should go where #10 is stated on the GSUSA Uniform Guide.

(Note – Badges and pins on a sash simply go in order (top of sash to bottom of sash) of Identification badges, bridging badge, pins, journeys, and other badges. Anything that does not fit on the front can be placed on the back of the sash. Sashes will not hold a lot of badges and vests are recommended if you plan to earn badges.)
