Fabric Requirements

Check the table below to know the fabric piece you need to cut the concave and convex cureve pieces depending on the size and the edge seam allowance chosen.
Desired finished size indicated as X (Ex: X = 4″) Square: sq. Width: w. Height: h.

Piece	Edge s.a.	Fabric needed
	1/4"	X + 1/2" sq. (4 1/2" sq.)
	1/2"	X + 3/4" sq. (4 3/4" sq.)
	1/4"	X x2 + 1/2" w. (8 1/2" w.) X + 1/2" h. (4 1/2" h.)
	1/2"	X x2 + 1/2" w. (8 1/2" w.) X + 3/4" h. (4 3/4" h.)
	1/4"	X x2 + 1/2" sq. (8 1/2" sq.)

Piece	Edge s.a.	Fabric needed
	1/4"	X + 1/2" sq. (4 1/2" sq.)
	1/2"	X + 1" sq. (5" sq.)
	1/4"	X x2 + 1/2" w. (8 1/2" w.) X + 1/2" h. (4 1/2" h.)
	1/2"	X x2 + 1" W. (9" W.) X + 1" h. (5" h.)
	1/4"	X x2 + 1/2" sq. (8 1/2" sq.)
	1/2"	X x2 + 1" sq. (9" sq.)

Let’s cut!

Check the fabric needed, align as indicated and cut by the finished size label depending on the shape and size you whish.
Remember all pieces has 1/4″ curve s.a. included.
