Lately I've been doing string piecing. I've worked on 2, one with batiks, one with non-batiks. Doing the first block, I was piecing diagonally on a foundation fabric. It stretched, so I'm adding left over phone book pages to the bottom of the block to keep them from stretching.
I've seen others work on string piecing a star on a foundation. The corner that becomes the star is all the same size and fabric,then the rest is just string pieced. And others working on a block with string piecing on the straight of grain (don't need foundation fabric for this), then place 2 pieces with right sides together, with stripes going perpendicular to each other, sew around the outside, then cut on both diagonals. Arrange the blocks as you wish.
I also have a bunch of bonus half square triangles left over from making snow ball blocks. Don't know the size of them. And I was cutting some scraps into equilateral triangles to use in a border.
I think most people use 2" or 2.5" strips/blocks, but I prefer making larger blocks,so I often do 3.5" strips or blocks.
