In a simple light aircraft you should not need a check list. Check lists are for multi-crew challenge/response environments, not memory replacements for the lone SEP pilot.
I've seen some PPLs sitting blocking a taxyway, or the fuel pumps, engine running, while they leaf through pages of bumph that would do justice to a Space Shuttle, not a simple PA28.
For heavens sakes SEPs are simple! Keep it that way! Do you outside and inside checks using the aeroplane; for instance, for internals do a left to right run around the cockpit checking what needs to be checked (not much in a simple aeroplane!).
KISS - Keep It Simple Stupid!
