There's a difference between wholecloth and trapunto. A classic wholecloth quilt is all quilting on one color fabric, usually white or ecru. The designs for wholecloth are very elaborate and are gorgeous when finished. You can buy wholecloth quilt kits with the design already on the fabric. A wholecloth quilt can contain some trapunto (which is padding behind certain elements of your quilt design). Trapunto can be done on pieced quilts also to give dimension to the design.

I made my daughter a white wholecloth quilt as a wedding gift in 1990 and she was thrilled with it. This was during the era when I only did hand quilting. Alas, no picture! The quilt is in safekeeping to be passed to my DGD when she marries.

I recommend you begin small with wholecloth, maybe a pillow or small christening quilt. There's a LOT of work in this type of quilting. Trapunto is fun and there are several good tutorials on YouTube. Some LAQers are skilled enough to do wholecloth with their machines...awesome!
