The time to square up your quilt top is after you have completed all the quilting. Here’s how to do it.

First, do not cut off the extra backing and batting around the edges. Instead, fold the backing to the front, over the batting and the quilt top, and hand baste it in place. This will prevent the edge of the quilt top from fraying during the next step.

Next, place your quilt in the washing machine. Use warm water with a high water level and a gentle cycle. Unless your quilt is soiled, you don’t need detergent. Detergents can react with your markers and might set them.

While the quilt is gently washing, cover a carpeted floor with several flat sheets or a mattress pad. When the washing machine stops, remove the quilt very carefully, because the weight of the water in the quilt could cause the stitching to break.

Lay the quilt right side up on the sheets. Take out the basting around the edges. Smooth out the quilt, making sure it is straight and flat.

Using a metal tape measure, measure the length of the quilt along the sides and down the center. If your edges are shorter than the center, stretch them to match the center. If the edges are longer than the center, ease them so they are the same measurement as the center.

Measure the width of the quilt along the sides and down the center. Ease or stretch the sides as needed to match the measurement at the center of the quilt.

Next, measure the quilt along each diagonal. If the two diagonal measurements match, then the quilt is square. If they don’t match, then stretch a corner to make the shorter diagonal longer. Ease the quilt so that the corners look square.

Finally, go back and re-do all the measurements to make sure your quilt is now square. When it is, you can leave it to dry.
