Phew! Inkscape decided to play nice, so the pattern is DONE! Yay! And it has a name, of course: Bramble Blooms. Inspired by the suggestions from Alice of futuregirl. The pattern should have found its way to her by now. Everyone else can get their hands on it right here. ;-)
Again, thank you for all your suggestions for the name! Crowd sourcing the name was fun!
