I don't remember the lady's name, but I caught the show. She was demonstrating what she called sister blocks: three identical pairs of blocks in different color ways. All of her strip piecing strips were 1 1/2", but she said that you could cut yours whatever widths you wanted. You could even mix up the strip widths if you wanted to.
I'm sorry I can't tell what the finished block sizes were, but the quilt had six blocks plus borders. It was a comfortable lap size quilt. Three of the blocks were in reds and oranges with the sisters in blues and greens, right?
