I take low budget quilting to it's lowest possible point. LOL. For lining, I often buy mattress covers that are cotton, polyester or a blend at thrift stores, remove the fabric that makes it fitted and then use it to fill a quilt. They are usually very low priced, especially if bought on half-priced day. They come in the right sizes for twin, full, queen and king beds, and are also good to line potholders, place mats, table runners, hotpads, etc. Used blankets, flannel sheets and other things can also be used in place of buying batting. Once you wash these items with a good long cycle and some bleach, they are safe and clean to use and shrinking is not a concern. Neither is wadding, bunching and other issues that occur with some battings. Since I have so far tied my quilts, this has been an important issue for me. These mattress covers come in all thicknesses and qualities and are almost always white. You can select a thicker or thinner one, depending on what you want the quilt to be used for.
The very thickest would perhaps be hard to hand or machine quilt, but are great for pot holders, hot pads and table toppers. They do take the large stitch quilting well.
