With the printed fabric you already used cut a 1 1/2" x 6 and a little strip. You need exactly 6" but I like to give myself a little extra. I cut one long 1 1/2" strip of shirting and sewed away. You see some of my printed fabrics I used 3". I tried to use up small pieces. Some I even used a 1 1/2" square. You will need two 4 patches of each color.
Lay them out on your wall watching the color placement. Assemble your four 4 patches to make a 16 patch block. Isn't it cute?! Continue until all 16 patches are made.
According to EQ it should finish at 24" but mine measures 25 unfinished. It should be somewhere in that ballpark.
If you want take a look at the original quilt again for quilting ideas. I noticed the cheddar blocks are quilted in a cross hatch and the prints and shirtings are quilted only on the diagonal. I like it!
If you want to make a larger size quilt and would like larger blocks here are a few measurements.
For an 8" Cheddar & Cracker block cut your center cheddar 6 1/8", your squares 2 1/2", and the squares to cut in half 2 7/8". For the side triangles you would cut a square 9 1/4", then slice on the diagonal twice for 4 triangles.
For a 6" block: 4 3/4" squares for cheddar, 2" squares, 2 3/8" squares to cut into triangles. For the side triangles cut a square 7 1/4", then slice twice.
If you want another size feel free to ask. It is pretty easy to change the sizes in EQ and give you the measurements.
