DO NOT IRON your squares if you have already cut them out...
Pin two togehter (or not) and sew together using a 1/4 inch seam. It is important to use this seam throughout the contruction of your quilt.
Sew the next block onto the first two and so on till you have it the length you want.
Press your seams toward the darkest fabric. Press down with a hot iron, no steam...
This should get your rows together...
Let us know when you want to get your rows put together and we then can help you there.
PM with any pertinent questions
