Scouts should wear their Cub Scout uniforms to the major scouting functions. 

This downloadable form shows the correct placement of the patches that you will need to get for the uniform.

If you need to buy the patches here are some local stores that sell them.

The Knox BSA Store

• 23 Turnpike Road (Rte. 9 North/Westbound side), Southboro MA

The Maynard Outdoor Store

• 24 Nason St, Maynard MA
• Stock patches, hats, neckerchiefs, shirts and more.

Or if you want to shop on-line, the Boy Scouts of America have an on-line store.
