Hi Eddie,
Yes--I use almost all scraps of W&N to make my raggeds--the batting for the rectangles is so small! I try to use everything--and the scraps come from trimming up quilts I've gotten back from the quilters.
Continuous seam--take a pile of squares to be quilted and get the first one under the machine...just as it's at the end, stick the next one under and go! Then the next and the next, until you have a kind of kite tail made. Once the pile is through, snip them apart and do the other way.
Sometimes I stop 1/2" from the end and lift the needle and place it 1/2" into the next piece--but it doesn't make much of a difference in the end.
I quilted lines on the striped fabric--thought Xs would look silly.
Hope that helps!
