Big O Quilt Block Instructions

Skill Level: Beginner

Our Big O quilt block is the second block in our series on the partial seams technique (the first is 'Bright Hopes').

This time we add connector corners at the end to change the look and create the 'O'.

If you'd prefer to skip partial seams, you can easily piece this block using the Shoofly block pattern. Simply change the color placement.

Big O looks terrific paired with an 'X' block, like the 'Cotton Boll', for a 'kisses and hugs' quilt. Perfect for a young child or new baby.

Let's get started!

Using the photo below as a guide, stitch on the bottom edge from the middle of #1 (the black arrow) to the edge. I do not backstitch at the start. These initial stitches are secured when you overlap your stitching at the end of adding the rectangles to the center square.

Here you can see my red stitching...

Press.

With RST, align the edges of the pieced #1/#2 with another #2. Stitch from edge to edge. No more partial seams to stitch until the last of the rectangles is added.

After sewing and pressing two #2s, the unit looks like this...

Add the last two #2s in the same manner. Remember to press after each.

At this point your Big O looks like this.

All that's left is to sew the remainder of the first #2. Use pins if it helps.

Sew, remembering to overlap your stitches by a 1/4" or so (the black arrow).

Press.

To finish the Big O, we'll use the connector corners technique.

Draw a diagonal line on the backside of all four #3 squares.

With RST, align one square in a corner and stitch on the line (black arrow). Notice I've switched to my open toe applique foot. It's easier to see the line and where my needle is going!

Repeat for the remaining corners.

Trim the SA a 1/4" from your stitching, on the side closest to each corner. Below you can see the process.

Finish by pressing just like in the two lower corners.

That's it! Your Big O Quilt Block is finished and ready for your quilt!
