I have never bought a Jelly Roll yet - still too new at quilting to explore that far - but I think I would like the Jr. j/roll (20), well blended (I am still learning color/pattern conception) and being able to buy a Jr. j/roll of the neutrals(?) like white on white or white and beige - to me "seems" very like-able and do-able to work with. (Back on my perch!) :-)
