round ends of dresden-blades

I posted a Youtube link to a tutorial that included 3 or 4 ways to finish the outside edges for desden plates.

I'll post it here as well:

Hi all :-)

Thanks so much for your answers, the link is great, even I understood, how to make it. lol

But Claire's idea with the water soluable thread is also great, one can make two blades in one go.
The only problem is, that I haven't been able to get this yarn here in Germany, and unfortunately I couldn't find it in the MSQC-shop either.
I've been looking for watersoluable thread for some time now, because I would love to try shadow trapunto technique..
Until I find some, I think I'll try the tip from the video first.

thanks a lot
