As I finish projects I cut the scrappy sized pieces (10" or less is my rule of thumb) into squares
1.5" and 2.5"
Then if I'm at lose ends in danger of starting something new, or chain piecing I use the twosiezes as leaders and enders.
Pretty soon I have pretty blocks.
That said, I have also made three Scrappy Trips quilts by strip piecing and they are cool too. It all works!
