i'm not really following you- but when i made one for my daughter i pieced a top, lightweight batting & a muslin backing- then finished it up with the 'duvet' back- sewn around 3 sides,(the top of the back is longer- folds over the top) (right sides together) turned right side out- top stitched around the edges- finished the fold part with buttons, button holes. came out great. her backing was pinwhale corduroy (her choice) so it is kind of heavy-but she loves it & it really turned out very nice...expensive looking...
