I think you've missed the point. You cannot submit to a double take at all. Double take submissions are chosen by woot. They're all shirts from previous derbies that received honorable mentions by woot staff.
You can submit to a regular themed derby, as long as the shirt fits within the theme guidelines. Next derby theme is "Bold". There will be a submit button once that derby launches so if your design falls under that theme, you can submit. Otherwise, you can always submit your design directly to woot and bypass the derby completely.
