Please don't take to heart posters who say that Tara doesn't read these forums. I'm sure Temp-tations has someone monitoring the comments and suggestions here. She is a very savvy business woman, and while you wouldn't get a reply here, I think your commenting here is very valid.
There are sets of smaller bowls like ramekin size, and there have been the set of 4 ovals that are smaller. Are you maybe looking for what is traditionally called a berry bowl in some older sets? I think that size would be great. I use the berry bowls in my other dinnerware brands all the time.
