I hope your vision of me over the weekend was stitching the zigzag on the edges of each of these pieces.
We aren't discussing how many at this point, especially as I am still working out the joining back together! But suffice it to say that each long side of front or back is 36 pieces. and with 4 sides (2 front + 2 back)...you do the maths!
So, the two piles needing to be stitched
and one of the piles which was already stitched.
The stitching is easier to do with the shoulder than the cutting was. (But it is tedious!)
My set up at the machine.
I use a blind hem stitch when I cover edges of things with zigzag. It helps the stitch to properly form over the edge without drawing the fabric up into a lump. My blind hem foot has a little bar, so the stitches form over the bar and then slide off it to the back as the piece goes along.
The little red bit at the front of the foot is adjustable for guiding your project edge along. For using the blind hem foot as a blind hem foot, it would be useful for getting it right for the 'bite' of the blind hem stitch.
You can see the threads I will be using. The dark turquoise is what I am using on the lilac fabric. It is much paler when seen as a single thread. I am not doing a very close zigzag. Just enough to hold the edge together and add a bit of glistening.
If I get it right, I can go from one piece to the next like quilters do with chain piecing.
