I came across some 3" squares in one of my scrap bins, so I chopped them into quarters. Each block yielded four 1 1/2" blocks with no waste. How handy and timely!
I did the math over lunch today, and according to my calculations I will need 1200 pieced 4 patches for a queen size quilt. I have to admit that I was actually a little disappointed that it wasn't a higher number. Maybe it's time to seek professional help? Ha! Anyway, that means that I'm about 25% done piecing the 4 patches. That's pretty encouraging!
