I also vote for having the border. It will frame your beautiful OBW nicely. Lovely top!

I would add a narrow black border and bind in black.

Loving your OBW and think that the border frames and sets off the kaleidoscope blocks. Good job.

that is beautiful and doesn't need any frame--I vote no border, just a black binding.

"Just casually whipped.together a OBW...no big deal...."

Incidentally - add another vote to the Yes Border team.
