I just finished piecing the top of my 10 minute block quilt. It took me longer than 10 minutes until I got into the rhythm but then it was okay. I decided to put sashing around each block & now I regret it because it has taken so much time to make sure all the seams match up. Looks great though, just a lot more time consuming. I think once you got 1 or 2 under your belt, you could sail through a quilt !! I am glad I tried this block.
