This looks like an all cover pattern. An antique white would do nicely.

Yes this pattern is in need of 14 counts aida cloth. Enjoy

Or 16 or 18 count...😊

Since this is a cover all pattern, you can use whatever color you like. I would consider antique white, ivory, or maybe a light khaki .

Platinum might be a nice color, too. Used it on a fractal...you know how they are... 😊
