  • Dark/Blue: 4 - 2.5" squares
  • Dark/Red: 1 - 2.5" squares

Sewing Directions:

Four-Patch Units:

Step 1:

Using the eight Light/White 2.5" squares and the eight Medium/Green 2.5" squares, sew together four Four Patch units.
In the picture below you can see the basic steps of construction:
  • Lay out two squares of each color and sew into two rows.
  • Press the seam allowances toward the Medium/Green fabric.
  • Sew the two rows together.
  • Press the seam allowances. I've used the tweak/twirl/furl method of pressing but you can press however you wish.

Step 3:

Layout the remaining Light/White 2.5" squares, the Dark/Blue 2.5" squares, and the Dark/Red 2.5" square as shown in the picture below. The unit is a typical Nine Patch block.

Putting It All Together:

Layout Ideas:

Here's the basic 4 x 4 layout using similar colors to the ones I used in the tutorial:
quilt 1
This version is the same as the one above except that I added in sashing and red cornerstones. There would be plenty of room to do some fancy quilting in the open areas.
quilt 2
Where this block really shines is when it's used as an alternating block with more intricate blocks. Here I'm showing the block with only two colors.
quilt 3
In this example, I used three colors that coordinate with the more intricate block.
quilt 4
Since the applique block has so many colors in it, I felt the 7-Grid Chain had to be scrappy! Love this one!
quilt 5
This is an on-point example. Also scrappy because the Dresdan plate has so many colors in it as well.
quilt 6
Here's a striking example using a black background and setting triangles in another on-point layout using just the 7-Grid Chain block. Very modern looking!
quilt 7
This on-point example is monochromatic - just dusty blue in light, medium, and dark tones. I also put in narrow sashing and cornerstones.

The 7-Grid Chain is so fast and easy to sew together! It can be used alone but it really works to showcase those more intricate and difficult blocks. You know the ones that you just can't bear to make another one! It works with block sizes that are divisible by 7 - so 7", 14", 21", etc. It is an odd size so when you need it, you need it!
