I finished all the whipping on the wedding rug yesterday, so today was the day to complete the four corners. (Yes, I missed the 12 12 12 birthday and am now aiming for Christmas.) This photo shows the corner before the point is cut off. I stitch across and then cut off the excess to reduce bulk. Below is the corner all basted and ready for whipping. I do not baste the sides before whipping, but find it is essential to baste the mitred corner.
Here is the corner half done and the fourth picture is the finished corner. It’s not often that I do corners, perhaps three times a year and each time I have to relearn a bit of the process. That is why I find the corners turn out better and more alike if I complete the whipping first, then do all four corners one after the other.
