many entries even in big quilt shows are created (pieced) by one person and quilted by another---it is not 'cheating' it is fairly common practice---lots of people (even award winning ones) do not quilt their own quilts.
it is also common practice (and kind of expected) for the quilt owner to give credit where due...and acknowledge /include the quilters name on their label and on their entry information...I often when visiting shows see beautiful quilts that say- 'quilt by_____________; quilted by;_____________
I've even seen a few of the quilts i've quilted for others entered...unless the catagory it is entered in clearly states it has to be all your own work....but i've been to lots of shows and have entered lots....and have not seen that distinction...even hand quilted quilts are at times quilted by someone other than the person who pieced the top. i know ladies who hand quilt for others and do beautiful work worth 'showing' !
