I'm a beginner beginner and just getting started on my first project, the adirondack table. And I'm stumped at step 1. The plans call for 1x3 boards and apparently these cannot be bought in my remote location. (I'm afraid I will run into this problem often.) The lumberyard said to get 1x4 and "just rip it" which sounded great at the time.
So now, exactly how do I do that? I have a circular saw and a huge learning curve so in your response please be detailed (and basic). Thank you for your time and patience! :)
