Taking a cue from Bonnie Hunter, I started using leader and ender pieces while sewing. I have a plastic container of squares pre-cut, light and dark, just waiting. At the start of sewing, I piece a light and dark square, and at the end, another set. Eventually, I use the two blocks together as leader-enders to make a four patch. This is while I am piecing another quilt. Most of my piecing is done on a Singer 301. I press the four patches, and with this quilt, I used the Square in a Square Method by Jodi Barrows to add the sides on. I made half the blocks with black print, the other half, white with black print. In the book that comes with the trimming tool, this pattern is called, Simple Simon. This quilt is loosely based on the pattern, as I used a four patch center, and different borders, but I got the black and white idea there. I sewed the quilt together on my Adironadack vacation with my Kenmore 158.1040. It is so compact, it easily packed away. I also started an I Spy Disappearing Nine Patch Quilt there, but I don't have photos yet. When I got home, I added the borders. I need to see a quilt complete before I decide on how wide and what color the borders will be.
