To the Vintageseamstress and other novice quilters...I've seen the videos and agree its a quick way to make pinwheels, there is another video she does for a quick table runner using the same principle...just one word of caution. When you make a block like this you end up with OUTSIDE bias edges. This makes the pieces of fabric fairly unstable, stretchable. Please when using this method starch heavily and handle pieces with extra care not to pull on them. You will end up with a mess. I do wish that this lady from the video would emphasize this fact. If you plan on doing this please do it first on a small project before diving in head first.
