Quilt Top: Mark the top of the quilt with a safety pin. Square the corners, making sure the quilt lies flat with straight edges. Make sure seams are at least ¼” and press (seams pressed open are best). Trim loose threads. If quilt is a light color, threads from the back will show through.
Backing & Batting: if provided by you, both must be 6-10 inches larger than the top. If pieced, seams for backing work best if they run horizontal to the top and bottom of quilt and must be sewn with ½” seam pressed open with selvedges removed. You can leave the selvedge on the top & bottom of the backing as long as those edges are even and the corners are square. Batting must be high quality to make it through the rollers without shredding.
Embellishments: Wait until your quilt is quilted before adding embellishments.
