It's called a disappearing 9 patch. Here is a tutorial I got the idea from:
You take 9 squares of fabric and sew them together in a grid of 9 squares. Then with your rotary cutter you slash the 9 patch in 1/2 lengthwise, and then widthwise. You then have 4 new patches. You rotate and turn the squares (which gives you infinate patterns to do...hell for me because I hate making final decisions), and match them together in a 4 square..then sew together to make a new patch.
Here is the fabric and the squares in progress...
Good grief, it's feast or famine for me in this blog world.
I will take the lime and the turquoise and make some skinny borders, and then accent it with a wide chocolate border...we'll see how it goes!
