QF Corner - Basic

General description of block: This is a half square triangle block with one side bisected.  It is the corner stone (no pun intended) for the Quilty Friends block of the month program and will create a secondary pattern of pinwheels when constructed correctly.  The directions for this block are written using the colors in the diagram above - in order for the pinwheels to appear you must use highly contrasting colors when you design your quilt.

Finished size of this block is 4" (4 1/2" actual, including future seam allowances)

Cutting directions: (12 pieces)

  • Red-
    • Cut 1, 5 1/4 inch square.
    • Sub-cut this square diagonally into 4 small triangles.
  • Yellow -
    • Cut 1, 5 1/4 inch square.
    • Sub-cut this square diagonally into 4 small triangles.
  • Other -
    • cut 2, 5 1/4 inch squares.
    • Sub-cut them on the diagonal into 4 large triangles for corner blocks.  
Piecing directions:
  • Sew one dark and one light small triangle together to make one large triangle.
  • Being careful not to warp the triangles, iron seams open.
  • Sew each set in the same order.  The finished large triangles should be identical.
  • Using the right angle to align the pieces, sew each two colored triangle to a large single fabric triangle. Trim the excess seam allowance (this should all be from the large single fabric triangle).
  • Being careful not to warp the triangles, iron seams toward the large single fabric triange. (The side with the least number of seams) Trim square to 4 ½ inches.
  • Make 4 identical squares
