Square Up Quilt Block Pattern

The square up quilt block is a simple four patch block.  I’ve made it here as a 12″ square finished size.

Cutting requirements for the square up quilt block

3.7/8″ squares:  two each in red and white, two each in red and yellow, one each in yellow and gold, one each in yellow and white

3.1/2″ squares four red

Place two squares with right sides together and mark a line along the diagonal.  Sew a 1/4″ seam either side of the marked line and cut along the line.  This will produce two half square triangle units which are now 3.1/2″ squares.  Press the seam allowance towards the darker fabric and trim the two corners where the fabric sticks out.

Lay the squares out in four rows of four.  In the middle place the yellow/white and yellow/gold half square triangles. Make sure that the yellow triangle is always on the outside.  Place a red/white half square triangle in each corner with the white on the outside, forming the corner of the block.

On each edge of the block, between the corner squares, place a red/yellow half square triangle and a red square.  Notice how each pair of yellow triangles combine to form a larger yellow triangle.  These are the spokes of the star.

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

Quilt ideas

Although I think that this block is a great design, it loses itself if used on its own in a quilt.  I’ve shown it here with sixteen blocks sewn together in four rows of four.

The simple addition of sashing makes a much better quilt, I feel.  Now the design of the block can be seen more easily.

Thanks for visiting my blog.

I hope to see you again soon.

  1. wow, Rose, I really like this pattern, I prefer it without sashing. really stands out. Hope your weekend was interesting and fun.

  2. The basic pattern minus the sashing has a 3-D effect, which I really like. Great quilts, both versions.

    • Thanks, June. I’ll have to go back and have a look at that version – you’re the second person to say that they prefer it.
