Three of the most popular shapes are the circle, the square, and the triangle. Squares are the easiest to sew together. Circles are a challenge for quilters because of their curved seams. Triangles are a challenge because the points should be even and sharp.

The names of traditional pieced-quilt patterns are as colorful as the fabrics used to make them. We will look at three quilts:

• a quilt with a pattern of circles called Double Wedding Ring 
• a quilt with a pattern made of crossing lines of squares called Irish Chain
• a quilt pattern of crossing lines of triangles called Tangled Cobwebs.
