Oy.
Definitely doable. But you'd have to map it out to figure out how many squares of each fabric you'd need.
Since the design most commonly blooms from the center - whether it's a rectangle or a square - it's really easily figure out the amount of each combo you need. I actually made a chart for all the permutations.
I've altered the pattern many times - more fabrics, less fabrics, increased the center portion to elongate it without adding another fabric but increase the size.
But if you decide to start the bloom in, say the upper right corner, will the next bands be wider?
- iow, would you double up?
-would you add a 5 more fabrics to reach the other side?
-would you bloom from the bottom left and have them merge in -the center? (actually - that would be pretty cool.)
If you just take a blank piece of paper and sketch out the abstact shape you want to create. Then it's easy then to figure it out the fabric quantities, and 9 patch combos.
Otherwise, you're making a ton of 9Patches you might not need, or you'll be short of some fabric because you need more.
Very interesting project.
