I had several 6 inch squares on hand, so I used 4 different fabrics and laid them out in the order I liked. I used a solid blue background and a pink binding.
1 A, B, C, D, A, B
2 D, A, B, C, D, A
3 C, D, A, B, C, D
4 B, C, D, A, B, C
5 A, B, C, D, A, B
6 D, A, B, C, D, A
7 C, D, A, B, C, D
8 B, C, D, A, B, C
9 A, B, C, D, A, B
10 D, A, B, C, D, A
I like to lay out my pattern on the ground and then stack my squares in order, however there are many ways to do this. So I had 10 piles of 6 squares.
Then I assembled the quilt top. I took my first stack of squares and sewed A to B right sides facing with a 1/4 inch seam, C to D right sides facing and A to B right sides facing. So you have a nice little train of 6 squares. Snip the strings. Then you unfold your 3 rectangles. Open AB and place CD on top of it right sides facing and sew your 1/4" inch seam, trim your edges open up your ABCD and place your AB rectangle in the right position right sides facing and sew with 1/4" seam. Trim your edges and when you open it up you have your first row. A, B, C, D, A, B all sewn together.
Repeat the process for the other 9 rows. Then press your seams open so they sit nice and flat. Once you have your rows sewn and pressed then you can attach them together. Put row 1 and 2 right sides together and pin starting in the center. Line up your seams and working from the center out place your pins at a diagonal so that when you sew it will stay in the right place and you will have crisp corners. Pin 1 to 2, 3 to 4, 5 to 6, 7 to 8, and 9 to 10. Then sew 1,2 section to 3,4; 5,6 to 7,8. Then the 1,2,3,4 to the 5,6,7,8 and the 5,6,7,8 to the 9,10. After your quilt top is all sewn together press open your seams.
Attach your border to the quilt top and again press open your seams.
Make a quilt sandwich: The back right side down extending a few inches beyond the dimensions of the top, batting lining up with the back, and the top layer is the quilt top right side up and pin them all together in place. I machine quilted this quilt, but you can tie at this point if you want. I machine quilted with a 1/4" border inside each square. Once quilted attach the binding.
For the Binding: 3" strips sewn together to make one long strip big enough to go around the entire quilt. Press the seams and then fold in half wrong sides together. Start about 1/2 way down a side and pin your binding to quilt leaving a 6" tail before you start to pin along one edge raw edges lining up with the raw edges of the quilt and sew with 1/4" seam. Miter your corner if desired. Then pin along the next section, miter your corner, pin and repeat until you reach where your starting point is leaving another tail. Open up both tails and mark where they will meet on both pieces Pin the tails right sides facing. Use a ruler and mark your seam line. Sew your seam line and trim excess fabric finger press open the seam. Fold in half and lay down flat along your quilt edge and pin in place. Starting a little behind where you stopped sewing before back stitch and sew the remaining binding in place extending past your original starting point and back stitching there also, securing in place. Snip all your loose ends. Flip the binding over to the other side and you can either hand stitch the binding using a blind stitch or you can machine sew in place. I have found using clear quilting thread works well to attach the binding to the other side. Make sure you move your needle and sew as close as you can to the edge while still catching all the fabric making a secure end.
