Press your quilt top. Make sure all loose threads are removed from the front. Are all your seams sewn together with no holes or gaps?
Did you have pieces that you had to ease in to make them fit? If so they may not be able to be quilted without creating puckers in the quilt.
Do your borders lay flat or are they wavy? If wavy, go to the Border page and see how to properly attach borders.
Turn your quilt top over and check the back. Are there any dark threads that need to be trimmed? If your quilt has light areas, those dark threads can really detract from the finished product.
Mark the TOP of your quilt (where it would lie on the bed) with a piece of paper marked "TOP". Attach the paper to the top of your quilt with a safety pin.
Your backing should be 100% cotton. If you have had to piece your backing together, make sure that you remove the salvages on the seams.
Cut your backing and batting at least 8" larger than your quilt top (4 “ on all four sides). Cut them as square as possible. If folded in half and laid on a flat surface, you should have 90 degree corners. It is helpful when you are piecing the backing that all pieces are the same length and edges are square. I can square your backing for you for $10.00. Be sure to allow extra fabric for this.
NOTE: The better job you do preparing your quilt top and backing, the better job I can do for you when quilting.
I carry many different types of batting --- Hobbs 80/20, Hobbs 100% Cotton, Warm & Natural/White Cotton, and Quilters Dream Select Poly batting.
