SueZQ from MN recently posted about a Manx Block. It is hand sewn.
Have you heard of a Manx Quilt Block?
Here is a link to a Youtube video that I have found to be helpful with the ManX Block as well.

Variations in ways to make the block are already showing up in my research. Diary of a Quilter blog says the width of the strips is from the base of your thumb to the bottom of your thumbnail. The Youtube video (white gecko craft lounge) says the width of the strips is the length of your thumb. The video also discusses using pearl cotton instead of thread because the sewing shows on the back and pearl cotton is more decorative. I can tell you that cutting with scissors or a rotary cutter is much better than nicking and tearing the fabric. That really distorts the weave on the edges.
