This is one of my favorite modern quilt designs – just half square triangles sewn together at random. And I really mean, at random. I didn’t worry about whether or not the slant of the seam was going one way or another – it’s the randomness that gives it so much character!
To make this quilt, I cut 11″ squares, then used this method to make a bunch of HSTs. After that, I sewed them into rows, pressed the rows alternating left and right, and sewed the rows together to make my quilt top. The finished HST size if 4 1/2″. You could also do this with a layer cake (or 10″ squares) and your finished HST size will be 4″.
I quilted it on my home machine using straight lines to go with the modern look of the quilt. I usually hand-stitch my binding, but for this one I did machine binding and even used a wiggly stitch (you can see in the second to last picture below).
