Pin design and background layers together securely as you move out from center. Measure distances when necessary to be sure placement is correct and adjust accordingly. Where design elements are supposed to match on straight and diagonal folds, make sure they do. This step is rather time-consuming but essential to successful completion of your quilt. Once you think placement is correct, check again .
Some final adjustments are usually necessary.
Your quilt top is now ready for basting. Loosen edges of background fabric from the work surface in order to baste. If you have been working on the floor, move quilt top to a table. Any commmercial sewing thread, preferably white, can be used. A long thin needle such as a Milliners needle is best for basting.
