I do believe that one "should" meet the suggestions of/on the batting for minimum spacing of the quilting.
I saw some donation quilts that were well designed, nicely pieced - but tied at about 18 inch intervals (each way). That is a bit "too minimalist" for my taste.
I currently do not have the skill set for the intricate quilting some can do - which I truly admire - nor am I motivated enough to either learn how to or acquire a long arm.
So - there may be just a touch of "sour apples" in my comment -
I do admit to feeling a bit self-defensive with my "plainer jane" quilting - but as long as a quilt gets finished and is usable - I consider it "a good thing" .
