I made this quilt. Different outcome, but same technique (I used 1 1/2" cut squares, finished at 1"). It is definitely do-able, and doesn't require a lot of experience, if you take it slowly. There are over 1600 small squares in my project.
I would probably make the black background of larger sections, not all 1 1/2". In my star, I graduated the outer background up to 4" squares, to reduce bulk and sewing time. I think it adds to the look - keeps your eye focused on the main project. I assembled mine in squares (not long strips). Started with 4-patches, then 16-patches, then 64-patches. By then, the squares are a more manageable size
I'd be happy to share more information - PM me if you have specific questions.
