With the palette you have now, grey and black, it almost equals white. Whatever your favorite color is, would look fabulous! I can see it with green (my sil's favorite), pink (my DGD favorite), red (DGS), blue (hubby), yellow (DD) even purple, well there you go, a rainbow LOL!

Lovely blocks! Perhaps a pop of color-lime green, hot pink, aqua, etc. in one block, and a thin accent border. Then a nice wide border of your chosen B/w.

Pale yellow is another option. Diane C.

I like as is too........but lime would do a pop. ;-)

I think a color would stand out like a sore thumb. That said, I would use the darkest of your fabrics for the binding, it would frame that beautifully. IMHO

I would use a white sashing. Either two white borders with a thin pastel-colored strip between or edge with the pastel border then the white border. Instead of the pastel, you could use black.

Great looking blocks! I would add lime green!! No kidding!!

A pop of colour in one of the blocks.

I think a white flange with a black border would set it and make it pop. If you had a bit of color in it, that would be one thing but you don't. Love your sampler!!

I like this. A small red border after the stop border, then a larger border of the fabrics you have in the quilt.
