A quick and easy quilt block, the Monkey Wrench is constructed using rotary cutting and speed piecing techniques.
Help, I need a quick review of Rotary Cutting and Speed Piecing.
Note: all seam allowances are 1/4" unless otherwise specified.
One background fabric
|one 4-7/8" x 9-3/4" rectangle of fabric A|
|one 4-7/8" x 9-3/4" rectangle of background fabric|
|one 2-1/2" strip of fabric B at least 11" long|
|one 2-1/2" strip of background fabric at least 11" long|
|one 2-1/2" square of fabric A|
|1) On the wrong side of the 4-7/8" x 9-3/4" background fabric rectangle, lightly mark a line 4-7/8" from the short side of the rectangle. This should divide the retangle into two equal parts. Next, mark a diagonal line through the center of the two squares as shown.
Instead of drawing on your fabric, you can also use Easy Piecing Triangle Templates
|2) Take the 4-7/8" x 9-3/4" background fabric rectangle and place on top of the 4-7/8" x 9-3/4" fabric A rectangle, right sides together and edges matched. Holding the two rectangles together, sew 1/4" from the marked diagonal lines as shown.|
|3) Cut the sewn rectangles apart on the marked line as shown. Press the seam allowance toward fabric A. This will form four half-square triangle units that should measure 4-1/2" square.|
|4) Piece the 2-1/2" strip of fabric B to the 2-1/2" strip of background fabric using a scant 1/4" seam allowance. Press the seam allowance toward the fabric B strip.|
|5) Using the rotary cutter, first straighten the short edge of the strip sewn together in Step 4. After straighten the edge, cut four 2-1/2" rectangles from the sewn together strips. The completed rectangles should measure 2-1/2" x 4-1/2".|
|6) Take two of the rectangles completed in Step 5 and piece together with the 2-1/2" square of fabric A as shown to complete the center of the Monkey Wrench block. Press the seam allowances toward the Step 5 rectangles. This completed unit should measure 2-1/2" x 10-1/2".|
|7) Take two of the half-square triangle units completed in Step 3 and piece together with one of the Step 5 rectangles as shown. Press the seam allowances toward the Step 5 rectangle. Repeat with the two remaining Step 3 half-square triangle units and the remaining Step 5 rectangle. This will form the top and the bottom rows of the Monkey Wrench quilt block. These units should measure 4-1/2" x 10-1/2" when completed.|
|8) Piece together the units completed in Steps 6 and 7 as shown to complete the Monkey Wrench quilt block. The completed block should measure 10-1/2" square which includes a 1/4" seam allowance on all sides.|
