A good place to start is SCRIPTURE. Keeping a "list" of do's and don'ts pretty much defeats the entire purpose of Sabbath.
Yeshua said in Mark 2:27 Yeshua said to them, "The Sabbath was made for man, and not man for the Sabbath.
We are to keep the Sabbath as a day of rest.
You will find all kinds of people telling you what is and isn't acceptable scripture says really 2 things... you are not to work and you are to sanctify it.
Sanctify can mean: Set apart, bless, make holy etc...
Yeshua dealt with this very issue when he asked the pharisee's if it was permissible to do good on the Sabbath. Even thought they technically observed Sabbath they missed the entire point of it. Its a joyous day of rest, spend time with your Father and relax, enjoy time with your family and friends... it should be something you look forward to... if it becomes something you dread because of this long list of things you can do or dont do... then you are missing the point.
Some get so off in the weeds they wont use a light switch. Okay, then you better unplug every appliance in the house before sunset on Friday if you think like that.
A good place to start is to observe it at sunset Friday....pray about what the Father wants YOU to do and dont let others tell you, that you have to do this, that or the other unless they can show you IN SCRIPTURE where they have arrived at abstaining from __________
Man has in his nature a real strong bent towards adding to what scripture tells us we are to be or not to be doing.
