Then comes the uneasy question at the<br \/>\nfabric shop: will this cut actually cover the back, or will you discover<br \/>\na shortage after trimming and piecing? Backing fabric can be one of the<br \/>\nlarger material costs in a quilt.<\/p>\n<p>The answer starts with the <strong>actual quilt top<\/strong>, not the<br \/>\nmattress label. A \u201cqueen quilt\u201d might measure <strong>80 \u00d7 90<br \/>\ninches<\/strong>, <strong>90 \u00d7 100 inches<\/strong>, or something entirely<br \/>\ndifferent depending on the drop, border and shrinkage.

Measure the<br \/>\nfinished top in several places<\/h3>\n<p>Lay the quilt top flat without pulling it. Measure width near the<br \/>\ntop, center and bottom; measure length on the left, middle and right.<br \/>\nRecord the largest useful measurement, especially if borders ripple or<br \/>\nthe edges are not yet perfectly square. The backing should accommodate<br \/>\nthe quilt as it exists, not only its intended pattern dimensions.<\/p>\n<h3 id=\"measure-usable-fabric-and-sketch-the-panels\">2. Measure usable<br \/>\nfabric and sketch the panels<\/h3>\n<p>Measure the fabric width <strong>inside the selvages<\/strong>. Sketch<br \/>\nrectangles representing the available width and planned cut length. For<br \/>\ntwo 42-inch panels with a half-inch allowance on both joining edges,<br \/>\nsubtract about <strong>1 inch<\/strong> from their combined width. For<br \/>\nthree panels, subtract about <strong>2 inches<\/strong> for two seams.<br \/>\nCheck that the joined panel still exceeds the backing target after<br \/>\ntrimming any uneven outer edges.<\/p>\n<h3 id=\"cut-full-lengths-and-label-the-orientation\">3. Cut full lengths<br \/>\nand label the orientation<\/h3>\n<p>Square the first cut edge gently; avoid stretching the bias or<br \/>\npulling a long edge out of shape. Cut each planned length. Mark its top<br \/>\nedge before rotating panels. Align any nap or one-way print before<br \/>\nsewing.<\/p>\n<h3 id=\"sew-sturdy-flat-backing-seams\">4. Sew sturdy, flat backing<br \/>\nseams<\/h3>\n<p>Remove the selvages from the joining edges so the tightly woven<br \/>\nselvage cannot pull differently from the fabric body. Place panels right<br \/>\nsides together. Sew long straight seams with a <strong>\u00bd-inch seam<br \/>\nallowance<\/strong>, keeping the fabric supported on a table. A walking<br \/>\nfoot can help stop one layer creeping ahead of the other. Press the<br \/>\nseams <strong>open<\/strong> so the backing rolls flatter and creates<br \/>\nless ridge under the quilting needle. APQS recommends this wider backing<br \/>\nseam, shorter stitches and open pressing for pieced backs.

Measure the width and length<br \/>\n<strong>again after piecing<\/strong>; confirm the required margin<br \/>\nremains on all sides of the quilt top. Make the two edges that attach to<br \/>\nthe frame straight and parallel. Mark the top edge and center if<br \/>\nrequested.
