I tend to think of a quilt (as opposed to a quilted whatever) as being big enough to wrap around or cover someone or something...ie baby quilt, lap quilt, bed quilt, dog quilt, doll quilt.
A quilted tote, quilted placemat, quilted coasters, quilted wallhanging, quilted toy, quilted tablerunner, quilted jacket, quilted hat, etc. are items that use the quilting technique in construction.
They are as much a part of the quilting family as a regular quilt, but they also may require some additional or different methods of completion.
If they are entered in a quilt show they are usually in separate categories from other quilts, which may also have several different categories.
