I usually use a different tool to help me speed sew magic corners (and half square triangles), but alas, I couldn't find them. What does that say? My sewing room needs some serious organization! Anyway, I grabbed my Clearly Perfect Angles tool. I hadn't used it before so I was anxious to see how it worked.
You can purchase them from New Leaf Stitches. Their web site even has some awesome videos showing you exacty how to use them.
You can chain stitch to your heart's content without having to pin. Just keep the point of your square on the middle line and ZOOM ZOOM!!!
See how flexible the material is? You can even leave them in place all the time while you are doing other sewing. They won't move or get in the way. How cool is that!!?!!
I have more than one sewing machine so I'm marking mine so I know which one goes with which machine. This one goes with my Bernina 1090 and my other one will go with my Bernina 440. Hey, I need to buy another for my Singer Featherweight!
