exploding block Missouri Star quilt company
I am making a quilt using this method and my christmas scraps. You will need two 4 inch squares and one 5 inch square of contrasting colors and or values for each small block, finishes at 6 1/2 inches. You will need 48 such finnished blocks to get the equivalent for twelve 12 inch finnished blocks. I have the same colors you described plus some black and some dark blue. also my fabric vary from vintage to modern. this looks so promising. I am close to finishing all 48 blocks and will hopefully start sewing them together soon. So easy and so much fun. Great stash buster. I'll try to find this thread back once I have a top sewn together.
Here is what came up when I googled exploding block quilts. This should give you a feel for how some colors combinations look like.
