I have now completed my stashbuster squares project and I am really pleased with it. In total, I made 70 squares and arranged them in a 7 by 10 formation. I sewed my squares together using a variation of the mattress stitch and I made a blanket/throw. The blanket could be left as it is, but I decided to add a simple white border.
The full details are available here. I have also included a video tutorial.
