Machine pieced Monkey Wrench Pattern using triangles and squares to form the 10″ Squares started in May 2019.  A friend from quilting mentioned that she wanted to do a monkey wrench quilt but all she had was directions for a twelve inch block.  Thinking about it I had always wanted to do one too so I got busy and figured out how to make a 10″ block.
Here is the preliminary drawing that maps out the shapes in light and dark that form the pattern.
4 shapes are used in this design.

Below are the Templates I cut out for her.  I made them out of cardboard.  They can be used in cutting out the shapes of fabric to form the pattern.  She wanted to make hers very scrappy.

Templates for pieces of the monkey wrench pattern

I have included the Math notes figuring the size of squares that the triangles can be cut from if you choose not to use the template.  When cutting diagonals out of squares It is important to consider which sides are cut on the diagonal as that side will stretch.  Diagonals should not form the outside edge of the larger square.  Also triangles need to be cut at least 5/8 ths of an inch bigger than the finished shape so that points don’t get cut off where seams meet.   One quarter inch for seam allowances for the small squares.  That is figured into these measurements.

Cut Shapes are laid out to form the pattern

Shapes are sewed together and pressed starting with the small light and dark squares
I managed to put all my squares together the same way accept one That one square is the reverse of all the others.  I will keep it that way and use it in the center.

I have laid out the 11 squares I have with the odd square in the center.  This pretty print presented itself at this time as I was pondering over how to lay it out.  I inherited it from my mother or my great Aunt.  It seems to me that it might serve as an anchor to hold the thing together since it has a lot of colors.  It is light and airy even though it is dark and it has a fresh painterly flow about it.  The floral pattern will keep the palette from going to far into that autumn and fall look.  I plan to quilt the interlocking shapes into the whole cloth pieces.

I am going to make 10 more squares and then see how it looks.  Those 10 squares will go down the sides and make it square.  At that point I will decide if my plan is working and if that is the case I will sew it together.
