years ago we made dozens of these---they were twin sized- made great 'travel quilts' you can make them any size you want. if you want to use pieced blocks by all means do so- I've never considered making them with a binding instead of putting them together right sides together- not sure how that would work-but would be a lot more work than the 'normal way' ...since they are fairly easy- fast projects i'm not sure why you would want to complicate them& make them so much more work- but you can do them any way you want- your project-
