If after quilting, the sides of your quilt are uneven, you may need to square up. Squaring up is trimming the edges of the quilt (carefully) so that the measurements are even. If too much needs to be trimmed, it may change the proportions of the quilt and skew the pattern. Squaring up may also refer to the need for adjustments to a quilt block to make it fit into the quilt pattern. Individual quilt blocks may need to be trimmed or stretched so that they align with other blocks correctly. Double-checking measurements and keeping an accurate seam allowance is the best way to avoid squaring up.
