Welcome to the board. I hope you are going to start on an easy pattern before you tackle those you showed to us. I consider myself to be a fairly good quilter but I would never start with one like those. Rail fence, around the world, or just a plain Jane diagonal quilt would be better to start on. Also a baby quilt would give you some experience in making a quilt. Just my opinion, don’t want you to get started and decide it wasn’t what you wanted to do.
