I love scrappy quilts! That's wonderful that you have fabrics with so many memories to work with.
This block is not an easy one. Do you plan to sew by hand or machine? Are you going to paper piece it? Or use freezer paper backing? Do you plan to rotary cut or use templates? I'm not sure whether I can be of any additional help, but if I can please let me know.
Just a suggestion - you might want to practice making the block using different methods to see what will work best for you. Good luck with the quilt.
