This is an instant download! Pearl In a Clam Fill is a very dense fill pattern, designed to be set between two boundaries. It can be cut to any size or shape. It is not recommended that you stitch this pattern smaller than the default size. I have made it quite large so that you may fill many types of quilting shapes. Because it is dense, it stitches quite slowly. Also there will be some shrinkage. You may wish to set your boundary on the outside a little smaller than the actual space, and you also may wish to enlarge your inside boundary just a small amount to account for shrinkage.
