I really think it all boils down too personal preference. I believe that if you found 3-4 colors or various shades of one color I think you will have a great looking quilt. Just remember crafting like this also gives you a chance to express yourself in a crafty way. Enjoy hope it turns out beautiful.

I think that it would be great in several different colors. Another plus would be using up odds and ends of flosses that you have acquired through the years.

I did one of kittens. I did the stitching on the kittens and a friend quilted it. There were I believe 12 squares. There were 2 kittens on each square, One I made black the other white. On the next one I reversed the colors. The flowers on all were opposites also. I looked up cats on the internet and got my colors from them. It sure was different and colorful. https://www.amazon.com/Stamped-White-Blocks-Pkg-Kittens-Flowers/dp/B009E3BUVC/ref=sr_1_1?s=arts-crafts&ie=UTF8&qid=1482340380&sr=1-1&keywords=embroidery+quilt+squares+kittens I also did hearts with colors to match on the same quilt.
