I have nearly achieved a mistake free table runner with the 60 degree triangle. I have to re-sew the middle seam for a better line. I did more research on the net and found more photos and a tutorial. I didn't save the link to share, sorry.
I have sewn all the yo-yo's in the photo while on vacation. I added several more tonight. This is a good project while it is warm out. I added several more yoyo-'s tonight.
