Castle Tower Quilt Block – Free Pattern

The castle tower quilt block is simple to make and would make up into a lovely quilt.  I’ve made it in the browns and reds of bricks. It is classified as a five patch block and I have made it as an 18″ square.

Cutting requirements

3.7/8″ squares:  six each in dark brown and cream, four each in light brown and cream, two each in light brown and dark brown

3.1/2″ squares:  four cream, eight dark brown

Making the castle tower quilt block

Use all the 3.7/8″ squares to make half square triangles in the colour combinations listed above.  Place two squares with right sides together and draw a line along one of the diagonals.  Sew a 1/4″ seam either side of the marked line and cut along the line.  This will give you two half square triangle units which are 3.1/2″ squares.

Lay the squares out in five rows of five.  There are three dark brown/cream half square triangles around each corner.  The four cream squares in the middle are surrounded by two dark brown squares on each edge.  There are two light brown/cream half square triangles on each edge of the square and that just leaves the dark brown/light brown half square triangles to go one inside each corner.

If you wanted to showcase a particular fabric, it would be possible to use a 6.1/2″ square in the middle where I have four 3.1/2″ squares.  In that case you would need to sew the squares on either side together in fours before sewing them to the central square.

Sew the squares together across each row and then sew the rows to each other to complete the castle tower quilt block.

Thanks for visiting my blog.

I hope to see you again soon.
