I always just cut and make one sample block before I go any further with a new pattern...just in case (1) I hate the block or chosen fabrics together, (2) there's an error in the written measurements or instructions, or (3) I mismeasured something. It's saved me a ton of work, fabric, time, and frustration over the years.
I also never cut the borders or binding until I'm ready for them. It's too easy for the measurements to be different from what was planned or for me to change my mind on fabric choices. There's just no way I would ever cut several projects ahead of time. Good luck and have fun if you decide to go that route!
