Judy and Brad Niemeyer designed the layout, instructions, and foundation papers for One, which is a pattern in the Quiltworx.com Leaf Series. The leaf series is a collection of patterns designed to teach quilters one of Judy’s latest techniques, which is curved paper piecing. The most recent coversheet was created using a Tonga Batik Mini Collections designed by Judy and Judel Niemeyer with Timeless Treasures called Gold Dust, Titanium, and Sandstone. A sewing technique called foundation paper piecing is used to assemble the units required to make this quilt. Curved piecing, traditional piecing, and appliqué are used to assemble the wall hanging after the foundation piecing is completed.
