I’ve done something similar. Here’s what worked for me.
On a design wall pin selvage strips to mark out the size of finished quilt.
Sort the blocks.
1. Size
2. Colors
3. Featured
With selvage strips, indicate what will be the top of the bed.
indicate a tic-tac-toe board within the quilt top space on design wall.
Place the largest, featured and most dominate blocks on design wall, spreading them out. Avoid placing them in the exact center. Avoid placing them in a square, in a line, all on one side, on the edge, or corner.
collect the next largest and spread them throughout the quilt space.
Consider how to sew this together. Adjust placement to make piecing easier.
Repeat these processes.
Tweek as needed. Since it’s not sewn, it’s possible to rearrange or start over.
