When I made the jack in the box quilt block I hadn’t really intended to make it into a quilt, but I was stunned at what happened when several of the blocks were sewn together so I kept going. The star in the middle was a real bonus. The quilt is 40″ square.
sixteen 4.7/8″ squares in dark and background fabric
eight 4.7/8″ squares in medium and background fabric
eight 4.7/8″ squares in white and background fabric
four 4.1/2″ red squares
sixteen brown rectangles 8.1/2″ by 4.1/2″
Making the quilt
The half square triangle units are made using the 4.7/8″ squares. Place two with right sides together and draw a line along the diagonal. Sew a 1/4″ seam either side of the line and cut along the diagonal. This gives you two half square triangle units. Repeat with all the combinations of 4.7/8″ squares listed above.
The basic jack in the box quilt block uses four half square triangle units as shown. The two dark triangles are placed side by side to create one larger triangle. Sew these squares together inpairs and then sew the pairs together to make the quilt block. Make sixteen of these.
Lay out four of the jack in the box blocks at a time with four brown rectangles and one red square. Note that the large dark triangle is in a different position in each block. Sew together the top two blocks with the rectangle for the first row. Sew together the two rectangles and the square for the second row and sew together the two blocks with the rectangle for the third row. Make four of these large blocks.
Sew the four blocks together in two pairs and then sew the pairs together. Stand back and gasp with amazement when the star appears in the middle where the four blocks meet!
The jack in the box quilt top is now complete and ready for layering, quilting and binding.
