I made this quilt a few months back combining some of my favorite prints in a fun, large scale design. I saw a lot of tutorials/patterns for plus-sign quilts that called for cutting all the fabric into squares and sewing them back together, but I didn't want to break up these prints more than I needed to so I made the plus signs with 2 squares and a rectangle.
I would suggest sketching the quilt blocks ahead of time so that you can figure out how many different fabrics you need to use, but I put together this brief tutorial to make it easier to figure out how to cut the squares and rectangles to make whatever size plus-sign you want with every plus-sign lining up just right. You shouldn't need a pattern to make this style of quilt.
The first step is to determine how big you want the plus signs to be. If you think about the plus sign as comprised of 5 squares (1 on top, 3 in the middle layer, 1 on the bottom) decide how big you want each of those squares to be. I made mine 6.5 inches, unfinished.
To determine the length of your (middle layer) rectangle, multiply the size of your unfinished square by 3 and then subtract 1. To be nerdy and algebraic... The long side of the rectangle = 3N - 1 where N = size of unfinished square. So, 3(6.5) = 19.5; 19.5 - 1 = 18.5 My rectangles were 6.5 X 18.5.
If you want a smaller plus sign, made up of squares that are 4 inches unfinished, for example, then it would be 3(4) - 1 = 11 inches. Your rectangle would be 4 X 11.
Once you figure out all the math and have your pieces cut, lay out the blocks to form tessellating plus signs and then sew all your rows together! It works up really fast - especially when you use larger scale blocks like I did!
I even had a few extra for the back.
