One more thing is that any time you are going to stitch on a bias, start sewing onto a small scrap of fabric first. Then chain piece onto your real fabric. Your feed dogs sometimes start feeding everything through kind of wacky if you don't start your stitching on something else. All those pieces you trim off of another block that are at least an inch square can be used. You can keep using the same scrap over and over again. Just toss the scrap in the trash when you're done.
