Accidental Quilt Block Variation – 2015

Back by popular demand, LOL, here is a complete tutorial for making what I call my Accidental Quilt Block variation.  I think I now need to find a “real” name for the block, because this version was not an accident but carefully thought out to make the cutting and piecing much easier.

This is Jelly Roll friendly, which also makes the cutting very quick and easy.   I chose to use three fabrics;  one with a pattern, and two that were mottled solids.  I’m going to label them fabrics A, B, and C for simplicity.  Here’s what you need to make this block:

Fabric A – cut 3 – 2 1/2″ squares

Fabric B – cut 2 – 4 1/2″ x 2 1/2″ rectangles

Fabric C – cut 4 – 2 1/2″ squares

Accident Quilt Block Cuts

Row One:

Sew 1 square A to the left end of 1 rectangle B using a quarter inch seam allowance.

On 1 square C draw a diagonal line across the BACK (wrong side) of the square.

Lay the square C face down on top of the rectangle B on the right end (opposite from where you sewed square A).  Make sure the diagonal line is going from the top right corner to the bottom left corner like below:

Diagonal Line

Sew on the drawn diagonal line on square C to attach it to the rectangle.  Using a ruler, lay the 1/4″ line along the stitched diagonal line.  Trim off the excess fabric which will give you a 1/4″ seam allowance like below:

Press the seams on this row toward the rectangle and you’ll end up with this:

Make another strip exactly like this one which will used for Row 3 of your block.

Row Two:

Take the remaining 2 square Cs and sew 1 to the left and right sides of the remaining square A.  Press the seams toward the square Cs.

You now have three rows for your block.  Lay them out like so:

Block Pieces-6

Sew the three rows together using a quarter inch seam.  The key here is that you only need to line up the seams for the end squares A with the row two squares C when sewing the rows together.  Because you pressed the seams in the opposite directions on each row you can butt the seams next to each other to line them up.  This is also called “nesting” the seams.

The end with the diagonal line should line up with the the other square C in the center row as long as you have sewn your quarter inch seams consistently and not stretched out your rows when pressing your seams.

Block Pieces-8

You now have a completed 6 1/2″ square block.  You can press your seams whichever direction you choose that makes it lay nice and flat.  You can even press them open if you desire.

I hope you enjoy making this block and designing your own quilts using it.
