The pattern is called Odori and it requires the creative grid spider web triangle. I think a 45 degree triangle should work. Just be careful in cutting the pieces that make the star shape. The tool has the markings to cut them. The fabric I used was all out of a stash of donated material, so it took me a little bit to find enough pieces to make this work. This quilt will be given to the Syrian Refugees that have made it here to the US. These are middle class families fleeing their war torn country, they have very little or nothing at all.
