Free biscornu pattern
This biscornu pattern has been inspired by Hungarial folk art.
It doesn't have a sharp corner, so it is going to have softer lines than the usual biscornu. There is a photo of another one I made in this post.
To whipstitch it together, just match the middle stitch of the cut-off corner with the middle stitch of one side of the other square and go around as usual.
I think it would also look lovely sewn together as a simple square.
Hope you like it. :)
