Below are six tips to help make the experience with your longarm quilter pleasant and successful. If you are unsure about any of this or have questions, just contact me - I'll be glad to help!!
Please press all seams on your top and back. Many times we accidentally flip a seam when pressing. Don't "iron" - this stretches your material and can pull the quilt top out of square.
Trim any loose threads on back and front of both the quilt top and the backing. This is particularly important on tops that have a light background. Dark threads showing through light fabric are not pleasant.
If you have lots of seams coming to a point, consider pressing all seams open; the less bulk, the better for your longarm quilter.
When you add borders, you must measure your quilt top through the center and cut two borders to that length. Pin in place, sew, press and measure through the center for the other length. This must be done for each and every border you add. It sounds tedious, but doing so should insure that your top will be square when you finish. Please do not just 'slap' a strip of fabric on for a border. Your border will be 'wavy' if you do. Puckers and pleats could result when your top is quilted.
The quilt back should be at least 6” wider and longer than the quilt top. This holds true for the batting also, if you supply your own.
Make sure the backing fabric is square. Squaring up the backing is not difficult. Fold the backing in half lengthwise. You may need to fold it a second time in order to fit it on your cutting mat. Use your rotary cutter and ruler to trim the edges even. Next fold the backing width wise and using your rotary cutter and ruler, trim these edges even. Be sure that the backing seams are pressed open.
