Gosh, I just love those pieces. Did you make them? They're going to look great.

If you're concerned about the grouted areas being too large, maybe you could cut some neutral color tess to put between your colored pieces? I love the grey of the carpet that you're showing the pieces on now. Would grey work in your color scheme for both the grout and additional tess to fill in?

If this were my project, I'd add background tiles - a solid color to avoid large grout lines AND to show off your great work. LOVE these colorful beauties that you've created. I mix half black and half gray to get a beautiful charcoal grout. While I LOVE black grout, I like charcoal a bit better - it seems to bring out the colors of the tiles. Afraid you'll have to make these decisions. Don't give advice - just say what works for me. This is gonna be beautiful.

I KNEW I would get great advice. I never thought to add additional background pieces, that would be a perfect solution. Thanks for the idea of gray for the grout. I feel sooo much better now!

Smile!!!!!!!!!!!!!!
