You certainly don't have to, but you are strongly encouraged to bring a kit to work on. Class members are going to do a brief show and tell; then, go to work on their own current builds. Class members should be able to learn from each other as they work. If you have not been in awhile, this should be a fun class. Last time we met this worked out well.
Just a reminder about the Revell contest, it doesn't cost anything and you can do something other than cars this year. All you have to do is send photographs so let's all participate. See revell.com.
Bring a friend, show and tell, something to work on and whatever tools/materials you will need to work with.
