BernieLynn wrote questioning the “L” part of the drunkard’s path block – she wasn’t seeing what I was describing. So here it is.
A drunkard’s path block consists of two parts: a “pie” or quarter circle and an “L” or complement to the circle:

You can purchase acrylic templates of various kinds; you can make your own.
To construct a template first you need to decide on a block size (remembering to add the outside 1/4″ seam allowance – hence 6 1/2″ (for a 6″ block) or 6″ (for a 5 1/2″ block) etc.).
Draw an outline for your block. Next construct a quarter circle (using a protractor, a plate, …) using a radius between 1/2″ to 2″ shorter than your block size, making sure the arc ends are symmetrical. This creates your “pie” shape. The line you’ve drawn is the seam line. The complement is the “L” shape.
To construct seam allowances you draw another line 1/4″ from the quarter circle arc on EACH side of the arc line (I use a different colour pen to draw these two lines to differentiate them from the original arc line). Using template plastic, trace the quarter circle piece using the arc line farthest from the apex of the arc – this is the “pie” cutting line. Reposition the template plastic and trace the quarter circle using the arc line closest to the “pie” corner – this is the cutting line for the “L” piece (it’s a smaller quarter circle).

You end up with two quarter circle templates, one a half inch larger than the other.

To cut the “pie” pieces from fabric, cut a strip the width of the 1/4″ circle radius (the length of one side); to cut the “L” pieces, cut a strip from the fabric the length of one side of the desired pre-trimmed block size – this will be wider than the strip for the “pie” pieces. [For my blocks I cut 5 1/2″ strips for the “pie” pieces; 6 1/2″ for the “L” pieces.]
In my block I’ve made my overall trimmed block size 1 1/4″ larger than the radius of the “pie” piece:

When I’ve finished sewing blocks together there will be a 1″ border around each circle or partial circle.

But you can construct drunkard’s path blocks that have no border around the quarter circle. These are a bit trickier to stitch because you are working with just 1/2″ of fabric on the ends of the “L” shaped piece to end up with a 1/4″ seam allowance for joining the blocks:

It’s all up to you and how you want your final project to look.
In this case I want the circles to be circumscribed within the blocks rather than touch the edges of each block as I did in Let The Trumpet’s Sound.
In my first drunkard’s path quilt I circumscribed the circles. My circles, this time, will be a bit larger in relation to the size of the block.

Excellent tutorial! Thanks
You’re welcome. Give a couple of test blocks a try. Let me know how you did.
I think perhaps for a throw pillow I was intending to make but it’s a ways down the list. Little girl clothes and a toddlers shirt up next
