ABSTRACT:
A transparent flat sheet template facilitates joining and cutting of pieces of fabric used to make conventional quilting units, prior to assembly of the units into in a quilt. The template comprises a first edge having a first straight edge portion and a concave edge portion, the concave edge portion being a portion of a circle. The template has second and third straight edges disposed perpendicularly to each other, and a fourth edge disposed parallel to the second edge. The template also includes an arcuate guideline which is generally similar in size and shape to the concave edge portion, and a grid of first and second sets of straight guidelines marked on the template. The first set of guidelines are parallel to each other and to the first straight edge portion of the template. The second set of guidelines are parallel to each other and to the second edge of the template. The straight guidelines are used to align the template with edges of a square of fabric. The concave edge portion facilitates accurate centering of a fabric circle on the square of fabric, and the arcuate guideline facilitates accurate cutting of the sewn fabric circle and square of fabric to produce quilting units.
