Just a little bit of thread ....
Just finished this the other day. It's actually a motif to be used to make a tablecloth but I didn't want to make 332 of them. So I just made one.
It's made with Size 10 thread and it's 7 3/4" from point to point.
If you think you'd like to make the tablecloth, the pattern is here:
