Borders frame the pieced center, but a rushed cut can leave one strip
\nshort or cause a border to ripple. The most reliable approach separates
\nfinished quilt dimensions<\/strong>, border cut
\nwidths<\/strong> and fabric yardage<\/strong>. Each answers a
\ndifferent question.<\/p>\n

\n

Enter your quilt-center size and chosen border width in the Quilt Border
\nCalculator<\/a>. Use the result to plan, then measure the actual top
\nbefore cutting.<\/p>\n<\/blockquote>\n

Decide
\nwhether the border width is finished or cut<\/h2>\n

A border planned to finish at 4 inches<\/strong> needs fabric
\nfor the seams that attach it. With \u00bc-inch seams on both long
\nedges<\/strong>, cut the border strip 4\u00bd inches wide<\/strong>. If
\nthe outer edge will be bound without another border, your pattern may
\nspecify a different visible width before binding. Follow its convention
\nand label your notes \u201cfinished\u201d or \u201ccut\u201d so you do not add the allowance
\ntwice.<\/p>\n

A 60 \u00d7 72-inch<\/strong> pieced center with a finished
\n4-inch<\/strong> border on every side becomes 68 \u00d7 80
\ninches<\/strong>. The border adds 8 inches to each dimension: four on one
\nside and four on the opposite side. That does not mean every strip is 68
\nor 80 inches long at cutting time.<\/p>\n

Calculate the strip
\nlengths in sewing order<\/h2>\n

For the straightforward method, sew side borders
\nfirst<\/strong>. Each side strip corresponds to the original center
\nlength, 72 inches<\/strong>, with seam allowance at both ends as
\nspecified by your pattern. After those borders are attached, the new
\nwidth is 68 inches<\/strong>. The top and bottom strips
\ncorrespond to that new width. At a \u00bc-inch seam on each short end,
\nexample cut lengths are approximately 72\u00bd inches<\/strong> for
\neach side and 68\u00bd inches<\/strong> for each top and bottom
\nstrip.<\/p>\n

Total strip length in this example is 2 \u00d7 72\u00bd + 2 \u00d7 68\u00bd = 282
\ninches<\/strong>. If usable fabric width is 42 inches<\/strong>,
\nseven crosswise lengths cover 294 inches before the seams joining
\nshort strips<\/em>. You may need an eighth strip if you join several
\npieces diagonally, deliberately avoid joins at corners, or have to match
\na printed repeat. The calculator gives an estimate; sketch every
\nindividual cut to check the actual layout.<\/p>\n\n\n\n\n\n\n<\/colgroup>\n\n\n\n\n\n\n

Measure through the quilt
\ncenter<\/h2>\n

A patchwork edge can be stretched from handling even when the
\ninterior blocks are the right size. Measure the quilt through its
\ncenter<\/strong> parallel to the border you will sew, then check
\nthe edge measurements. If the edge is longer, pin the border at the
\nends, middle and quarters and ease the fullness between the pins. Avoid
\nsimply cutting a strip to fit a stretched edge; that can lock waves into
\nthe finished quilt.<\/p>\n

For a long border made from shorter fabric lengths, join the pieces
\nbefore making the final measurement. Press seams flat. If several seams
\nare unavoidable, distribute them rather than stacking joins at the same
\nplace on all four sides. A directional fabric might require you to cut
\nalong the length of the bolt instead of across it; compare the
\nappearance and yardage before buying.<\/p>\n

Check the border on the
\nfinished quilt<\/h2>\n

Lay the attached side borders flat before measuring for the remaining
\ntwo. Confirm the new width in more than one place. Pin the top and
\nbottom borders without pulling either layer. After sewing, press gently
\nwithout stretching a wet or hot edge. Re-measure the finished top; this
\nfinal size is the input for backing<\/a> and
\nbinding<\/a>
\ncalculations.<\/p>\n

Mitered borders, cornerstones, multiple concentric borders and pieced
\nmotifs need a different cutting plan. Calculate one border round at a
\ntime, using the dimensions after the previous round. Do not multiply a
\nsingle \u201cborder length\u201d by four when top and side strips attach at
\ndifferent stages.<\/p>\n

Common questions<\/h2>\n

Why are my quilt borders
\nwavy?<\/h3>\n

Often a strip was cut to a stretched outer edge rather than a stable
\ncenter measurement, or the border was stretched during sewing or
\npressing. Compare center and edge measurements and ease the top evenly
\nalong a correctly measured strip.<\/p>\n

How do I calculate two
\nborder widths?<\/h3>\n

Add the first border to both sides of each dimension. Use that
\nnew finished size<\/strong> as the starting center for the second
\nborder. If the inner border finishes at 2 inches and the outer at 4
\ninches, the total increase is 12 inches<\/strong> to width and
\nlength.<\/p>\n

Should I buy extra for
\nstripes?<\/h3>\n

Yes when stripe placement, matching or one-way orientation matters.
\nThe amount depends on the print repeat and how many joins you need. Lay
\nout the intended cuts on paper and add the required repeat length before
\nrounding yardage.<\/p>\n","protected":false},"excerpt":{"rendered":"
