LORELAI: Well, the quilting convention is sitting down to tea.
MICHEL: Uh, I’m doing internal cartwheels.
Quilting is the process of sewing different pieces of fabric together to form a multilayered quilt, which may be simple in design or a complex piece of art. There are numerous quilting societies in the US, and the inn is currently hosting a quilting convention.
Cartwheels [pictured] are an acrobatic maneuver commonly performed in gymnastics, as well as cheerleading and certain types of dance, including classical Indian dance. It is performed by bringing the hands to the floor one at a time while the body inverts. The legs travel over the body trunk while one or both hands are on the floor, and then the feet return to the floor one at a time, ending with the athlete standing upright. The phrase “performing cartwheels” is sometimes used metaphorically to mean that someone is exuberantly happy and excited. Compare when Lorelai said she was mentally doing a Jig.
