Magic square quilt block


This quilt block goes by the lovely name of Magic Cross.  It is attributed to Nancy Cabot, a columnist in the 1930’s who brought us so many delightful quilt block designs.  It is made entirely from half square triangles and I have made it from 2.7/8″ squares of fabric to give an 8″ quilt block.

Cutting requirements

To make each quilt block you will need eight 2.7/8″ squares in the light fabric, two in the dark and six in the green fabric.  You will need to place one light fabric square with each of the dark and green squares.

Making half square triangles

Making half square triangles


The half square triangles are made using the usual method of placing two 2.7/8″ fabric squares with right sides together and marking a line along the diagonal.  Sew a 1/4″ seam either side of the marked line and cut along the line.  this produces two identical half square triangles.  Press the squares with the seam allowance towards the dark fabric and trim the corners where the edges of the triangles stick out.  This helps reduce bulk in the finished quilt block.

When you have made all the half square triangle units, place them as shown with a dark triangle in each corner and the other half square triangles arranged to give a light coloured square in the middle and four green shapes.  I always think of these as rosebud shapes.

Sew the rows together

Sew the patchwork squares together across each row and then sew the rows together.  Make sure that the seam allowances face in opposite directions where two seams join.  This again helps reduce bulk.  The great thing about having the dark triangles in each corner is that when you sew several of the quilt blocks together you will find dark squares forming where the corners of the blocks meet.  That completes the magic square quilt block pattern – such a pretty block and so simple to make.
