Ok, final cut. :P This shows the patched triangles and only using 8 fabrics. I am not totally sure that the scale of the large floral is right but I will fussy cut it so that the motif is centered and oriented the right way. I'll get them ordered today.
The overall size of 72"x72" is dependent on what size the border repeat is, which I haven't really looked for yet, but this is based on 6" wide. The next row is 6" blocks, then 12" blocks. The inner red border is 1 1/2" and the center medallion is 21".
